Let’s celebrate AMC’s 150th Birthday – join us for this leg of the AMC 150 Relay in Maryland! We'll walk a 7.1-mile section of the WB&A Trail. This rail-trail was converted from an electric commuter railway that served Washington, DC, Baltimore, and Annapolis. The trail winds its way between Prince Georges County and Anne Arundel County, offering a mix of woods, water, and residential communities along the asphalt path. A bridge across the Patuxent River was completed in Spring 2025, now linking Prince George’s County and Anne Arundel County. The trail offers a peek behind the curtain of suburbia, with marshy wetlands, woods, bridges and tunnels, along with some trail sections that pass through residential neighborhoods and some road crossings. Participants should expect a mostly relaxed walk on pavement with little elevation, plus a mix of sun and shade exposure. Please bring a lunch or snack and ample supply of hydration fluids for a four-hour or longer activity, as we will take a lunch break about halfway. Dress for the temperature, with long pants for tick protection and sturdy running/walking shoes recommended. This hike is rated Moderate for its distance. Bathroom facilities includes a bathroom at the Riverdale Community Center at start and possible port-o-potty at the end. There may be others along the trail, but reports are that such facilities are inconsistent. Will update closer to the date. There is a porta-potty at the end of the hike on Electric Avenue. This activity is scheduled in conjunction with Appalachian Mountain Club’s 150 Relay celebration. From March to October, volunteers from AMC are offering a succession of hikes and other outdoor activities from Virginia to Maine, to commemorate the 150th anniversary of the organization’s founding in 1876. Though historically rooted in New England, over time AMC has expanded and established regional chapters through the Mid-Atlantic, including today’s host Potomac Chapter.

Hello Everyone! This is the make up date for the national portrait gallery in DC since I cancelled the event in January that was supposed to happen due to snow! My advice to get there is take the metro which should be easier to get there! We will meet outside of the gallery building and then walk in you may go at your own pace we do not have to stick together!

Let’s celebrate AMC’s 150th Birthday – join us for this leg of the AMC 150 Relay in Maryland! We'll walk an 8.3-mile section of the WB&A Trail. This rail-trail was converted from an electric commuter railway that served Washington, DC, Baltimore, and Annapolis.

A bridge across the Patuxent River was completed in Spring 2025, now linking Prince George’s County and Anne Arundel County. No dogs. This is a through hike that will require making shuttle arrangements.

Severe weather such as heavy rain or thunderstorm will cancel, drizzle will not. If in doubt, or have any questions, contact leader by 7 AM day of hike. Leader Desiree Smith/ As of mid-March, no bathrooms at the start/stop points or along the trail so plan to stop for a bio break on your way to the start.

**NOTE TO PROSPECTIVE RIDERS; RIDE MAY BE CANCELLED IN THE EVENT OF LOW INTEREST/SIGN-UP.** [https://ridewithgps.com/routes/45899232](https://ridewithgps.com/routes/45899232) 26.1 miles. Lunch is at the Great Falls overlook 18.2 miles into the ride. There are toilets at Great Falls and Fletchers' Boathouse. We will e-bike from Glen Echo Park in Maryland to the majestic Great Falls. We will be biking on the Capital Crescent Trail, the C&O Canal pathway, and McArthur Blvd with separate biking lanes. This tour captures the essence of adventure and natural beauty. We will be meandering alongside the serene Potomac River and the C&O Canal, offering E-bike Lovers an unparalleled opportunity to immerse themselves in the lush landscapes that define this region. Glen Echo Park, with its rich tapestry of cultural and artistic heritage, serves as the perfect prologue to a journey that gradually unfolds into the wild, untamed beauty of the Great Falls. The route is just over 26 miles on gravel and asphalt. The gravel is compact. If you don't like the gravel on the C&O Canal pathway, this is not your route. Entrance to the Great Falls National Park is for free as we enter from the C&O Canal. We park at the large parking lot off Oxford Street, NOT at the smaller lot at McArthur Blvd. Please bring snacks, lunch and plenty of water. FYI: Ride With GPS E-bike Lovers Club membership is now for free as [www.ebikelovers.com](http://www.ebikelovers.com/) generates sufficient income from ads to cover the costs.

This event empowers each participant to take the lead, as there are no designated bike leaders within E-bike Lovers. We all embrace the role of leaders in this self-guided experience. Please RSVP only if you are coming so we know how many E-bike Lovers will participate. We enjoy a nearly 100% RSVP success rate. Thank you so much for your help!

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Digital Device Detox,”** a guide to breaking free from the addictive and destructive powers of social media and apps, with Jillian Tucker, licensed clinical social worker in private practice, adjunct professor of clinical social work at Columbia University and New York University, and therapist with nearly 15 years of experience in addiction treatment and behavioral change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox](https://events.ticketleap.com/tickets/profsandpints/northern-virginia-digital-detox) .] Many of us have had the same experience: We’re trying to get things done and stay focused on the positive in our lives, but we can’t stop looking at a cell phone that tells us that we live in troubled times, that everyone else is better looking and having more fun, and that escape awaits in the worlds of Candy Crush or Pokémon Go. Maybe it’s time to find effective ways to loosen the grip of that cell phone and rediscover the happiness that comes with using digital devices less. Join Jillian Tucker, who previously has given several excellent Profs and Pints talks related to mental health, for a crash course on how to restore balance in your relationship with digital devices to ensure they’re simply tools you use rather than instruments through which other people use you. She’ll start by discussing social and mental-health trends connected to the use of digital devices. We’ll delve into the specific ways that their overuse can be biologically and psychologically harmful and leads to division, depression, anxiety and anguish on an individual and societal level. Professor Tucker also will look at why digital habits are hard to break, citing neuroscience and what we know about behavioral addiction. You’ll learn the many ways in which devices and apps are deliberately designed to be hard to stop using. You won’t be urged to just chuck your cell phone, though. After all, such devices can keep you socially connected, be sources of joy and learning, and even save your life if you need to summon help in an emergency. Instead, we’ll look at effective strategies for reducing digital device use, considering approaches that treat the overuse of such devices as “addiction” but moving beyond them to consider more nuanced ones as well. We’ll explore how to find our core motivation to change and how to carry out a change plan. We’ll consider how those who failed in past attempts to reduce digital-device use can overcome impasses in their effort to change their behavior. We’ll discuss ways to minimize the feelings of inconvenience and withdrawal that might come with reducing digital-device use, and we’ll discuss strategies for regaining the social skills and reviving the in-person strategies that our device use had compromised. You’ll learn how the same conditioning and power of habit that got us using our devices so much more also can be harnessed to help us use them much less. You’ll learn how to curate and enhance the positive aspects of digital devices, to help maintain them as a source of connection, joy, humor and learning and keep them from causing you unhappiness or stress.

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
