Happy BDay GRASP - at Andy's Pizza
GRASP started on April 27, 2022 - exactly 4 years to the day and at this very location! (formerly Mod Pizza) Don't miss this opportunity to celebrate our community and see friends old and new while enjoying pizza that has become quite a hit in the DMV area! Andy's serves pizza by the slice and also wine by the glass or bottle. Two slices of pizza and a coke cost about $12.
It all started with a ball of Trader Joe’s pizza dough. Over nearly a decade, Andy Brown has refined his recipe from semihomemade to a from-scratch crust that ferments for 72 hours before it’s baked in a hot stone oven. This location, in Kentlands, is the newest but Andy’s is quickly mushrooming around DC and NoVA. With its pliable crust, tangy tomatoes, and high-quality cheese, this is one of the most awarded pizzas in the DMV.

NoVABeerSec - April 29th @Aslin Beer Company (Herndon, VA)
The next NoVABeerSec event - "Informal Gathering of Security Minds Over Beer" will be Wednesday, April 29th, 5:30PM til 7:30ish at Aslin Beer Company - Herndon Taproom (767 Elden St., Herndon VA 20170).
**Venue for April:** Aslin Beer Company (https://www.aslinbeer.com) - Aslin Beer Co. was founded in 2015 by Andrew Kelley and Kai Leszkowicz. The name, Aslin, comes from the family that connected Andrew and Kai through marriage; they each married a daughter from the Aslin Family. Andrew’s professional background was in finance and consulting, while Kai worked in public service. They bonded over a shared interest of craft beer and home-brewing, which eventually lead to the idea that “We can do this too.”
**Additional Info:** We are an inclusive group, so if we missed anyone please let us know or if you want to bring your significant other/spouse please do. We do know there are folks that have changed roles since we last met so please also let us know if we need to add new contact info for people. Have a great week and see you later this month!
Cheers,
Rinaldi Rampen & Mike McCabe
of @NoVABeerSec

Photograph One A Day (31 Day May Project)
**The rules are simple:**
Take photographs **Each and Every Day** and post your best **ONE** (1) shot of the day - **EACH DAY** for **April**. If you happen to miss a day or two (life happens), it is **OK** to catch up and upload the photos for the days missed or just skip those days.
**Please don't post over 2 to 3 at a time**. This is part of the learning process.
**DO NOT POST TO THE ALBUM *UNTIL* AFTER 05/01/2026**.
Please use a browser like Chrome and the Meetup.com website to post the images, as **the Meetup app does not handle albums very well**.
Towards the top-left of the page is a link to **Add Photos** for uploading your photo to the album. **CONFIRM** **that your photo was added to the correct Album.** Remember to post your **best photo (JUST ONE)** you took every day on that day! **DO NOT POST PHOTOS FROM ANY OTHER TIME!** If you have time to post an older image, you can take a new image and post it. Be creative.
Please **add a caption** to know how far you are in the process. After you upload the image you took that day, find your photo at the end of the album, and edit the caption to state the day and total of days in the month like this:**?/31**. You can add the title of the image if you wish. A good title can make a photo! So, your photo for the **May 1st** caption would be "**1/31: My great photo!**" \*\* Adding a caption helps you keep track of where you are in the month. It does help.
The purpose is to have fun and get in the habit of shooting every day. Learn to use your camera. Read your manual and test out a new feature you have never used before. Sometimes picking a theme/project can help focus (pun intended), like flowers, your pet(s), a lens you haven't used in a while, or whatever your passion is. Or try something new...
The **end date is 05/31/2026**. Meetup.com does not allow events to be longer than 2 weeks.
Other images that were not taken by you will be removed. Please keep the images family-friendly. You need to be a member of the Virginia Beltway Photography Group.
I look forward to seeing how far people go and grow as better photographers!

Open Bar & Seminar (Free but RSVP required)
After hosting successful events, I always think that we could have done better and relate it to our day to day life and make it educational. In this connection, I wanted to show off my investment and trade hat and organize series of Happy Hours around Investment & Trade.
We will have speakers from different sectors and industries, at each Happy Hour. At this particular event, the speakers will discuss Retirement Saving (With An Overview of Interest Rate & Housing Market).
Topics will include:
• Today’s retirement savings challenges and approaches
• Sources of income in retirement
• Proper investment strategies
• Current interest rate environment and what to expect going forward
• State of the housing market
The address will be sent to members, who RSVPed, before the Event.
Enjoy!
A MAFN / NOVA Scribes Facilitation Open House!
What does it look like when ideas come to life?
Join NOVA Scribes and MAFN for a full-day, in-person open house where the public is invited to step inside the world of facilitation. This is a come-and-go experience designed for curiosity, exploration, and conversation. Whether you are new to facilitation groups, you are welcome.
The space will be set up as a "theater in the round," (see the image) with facilitators working live around the room. Throughout the day, you will see different techniques, styles, and modalities demonstrated in real time, from visual templates, facilitation tools, and decision-support methods. You can observe, ask questions, and engage directly with the practitioners as the work unfolds.
**What you can expect**
* Live demonstrations of facilitation techniques
* Multiple practitioners working simultaneously, each with their own approach and style
* Short, informal demos and tiny teaches that explain how and why specific techniques are used
* Opportunities to talk one-on-one with experienced facilitators
* A chance to see how facilitation can support sensemaking, alignment, and group dialogue
**What you might explore**
* Methods and templates for planning, strategy, and reflection
* Facilitation methods that support participation and decision making
* Tools, materials, and setup considerations for live work
This open house is designed to be accessible, hands-on, and inspiring. You do not need to stay all day. Come for 20 minutes or stay for hours. Watch ideas take shape. Notice how facilitation can change the energy in the room. Ask the questions you have always wanted to ask.
If you have ever been curious about how facilitation works and supports groups, this is your chance to experience it up close.
**Open to the general public. No prior experience required.**
We’re not charging for this workshop, but we will be asking for donations!
