Volunteers are needed for the **[51th Annual One Day Hike](https://www.meetup.com/sierrapotomac/events/312467688/?isFirstPublish=true)** (ODH). The ODH is a fully supported event that requires about 100 volunteers to put on and pull off. Volunteers must be enthusiastic, dependable, and hardy — showing up to work on time, *regardless of weather*. First-time volunteers get a free ODH T-shirt as a token of appreciation. Many volunteers are former ODH'ers paying back some of the help they received, and/or are family and friends of a hiker. If you are a veteran volunteer and want to reprise your role or would like to try something different, if you are an interested newbie, or if you just need more information about volunteering, email Mike Darzi (Mike.Darzi@Gmail.com) — *Please do not instead RSVP, message, or comment.* Photo albums of previous ODH's: **[bit.ly/MWS-ODH](https://bit.ly/MWS-ODH)**. **1) SUPPORT-STATION VOLUNTEERS** are needed to man/woman stations that provide food, drink, and assistance to hikers. If you are interested, let us know your preference in terms of time of day and amount of time you are willing to help. The more flexible you are in terms of location and time, the better. Except for the first three stations (through Edwards Ferry), you do not have to stay for a station’s entire period of operation, although that is preferable, and — yes — many volunteers serve at more than one station. The stations are: * Old Anglers, 5 to 7:30 am * Seneca Creek, 7 to 11 am * Edwards Ferry, 9 am to 2 pm * Whites Ferry, 10 am to 3:30 pm * Monocacy, 11 am to 6 pm * Point of Rocks, 1 pm to 8 pm * Brunswick, 2:30 to 10 pm * At Harpers Ferry and Bolivar (5 pm to midnight), where volunteers are also needed to guide hikers along the towns’ route. If you are willing to take on especially challenging tasks, we need you! Let Mike know. **2) BIKE PATROLLERS** are needed to ride their bikes to check on hikers all along the (mostly) unpaved route, providing assistance as needed. Patrollers are needed from about 6:30 am to midnight. If you are interested, or for more information, email Bike Patrol Coordinator, Jeff Comer (Comer.Jeffrey@Gmail.com), or Mike. **3) FIRST AIDERS** that can administer first aid to hikers as needed at major support stations. If you have first-aid or medical training, we’d love your help. If you are interested, or for more information, email First-Aid Coordinator, Jason Hauf (LJHauf@Gmail.com), or Mike.

[Book Your Classes by Clicking This Link! ](https://crowndancestudio.com/group-classes/) Take a deep dive into the world of Latin rhythm with our **Level 2 Bachata workshop from 1:30 PM to 3:00 PM**. This 90-minute intensive is crafted for dancers who have moved past the basics and are ready to refine their body mechanics, intricate footwork, and partner connection. **For $25,** you’ll receive focused, high-value instruction that bridges the gap between foundational steps and social dance mastery, ensuring you leave the studio feeling confident and inspired

The **One Day Hike** comprises two concurrent, non-competitive hikes of 100 and 50 kilometers that follow the C&O Canal towpath, and end at Bolivar, WV. The 100 km event (100K; 62.1 miles) starts at 3 AM from the Thompson Boat Center parking lot in Georgetown, DC; the 50 km event (50K; 31.1 miles) starts at 10 AM from Whites Ferry, MD. Both hikes proceed along the towpath, crossing the footbridge into Harpers Ferry after mile marker 60. The ODH has been held since 1974. During the hike, hikers pass through eight support stations, manned by volunteers (see [volunteering information](https://www.meetup.com/sierrapotomac/events/312467618/?isFirstPublish=true)), where they receive food and drink and, if necessary, first-aid assistance. While on the trail, they are monitored by volunteer bike patrols. Hikers must arrive at support stations by cut-off times or are required to drop out, and must finish by midnight. *ALL HIKERS MUST BE PRE-REGISTERED.* Photo albums of previous ODH's: **[bit.ly/MWS-ODH](www.bit.ly/MWS-ODH)**. **REGISTRATION:** Registration costs $95 and is done on-line starting Wednesday, February 11, at 5 pm (5-time finishers may register early starting Sunday, February 1, at 5 pm). Note that registration closes when the 350-hiker limit (100K+50K) is attained, which can occur within a few hours. See registration [details](https://drive.google.com/file/d/1niIsqRVC8Zl72JzAvBonqlzg4TLWiaGH/view?usp=sharing). **UPDATES:** For hot-off-the-press, official updates regarding registration and other information, join the ODH email list by sending a blank message to OneDayHike+Subscribe@Groups.io. For general information, check out [OneDayHike.org](www.OneDayHike.org). **TRAINING HIKES:** The Sierra Club Potomac Region Outings ([SCPRO](https://www.meetup.com/sierrapotomac)) organizes training hikes in the weeks leading up to the ODH. Although open to all, these hikes are specifically designed to prepare you for the ODH — they become progressively longer, they follow routes with relatively easy trails that are generally flat, and hikers walk at their individual paces. Longer training hikes also allow shorter options for 50K trainees. Doing these training hikes, or following a similar regimen on your own, is the best way to improve your chances of completing the ODH. Training hikes will be held from every Saturday from January 10 to the Saturday prior to the ODH. They are free, and are held at many venues in or near DC, so it’s a great way to explore this area on foot. On these hikes, you will get to meet other ODH hikers and learn their, or share your, tips on long-distance hiking. Each training hike's details will be posted on SCPRO's [Meetup](https://www.meetup.com/sierrapotomac) page each week, as well as announced on the email list (see UPDATES above). **VOLUNTEERS NEEDED:** About 100 volunteers are required on hike day to help run the ODH. We need reliable, enthusiastic people to man the support stations, patrol the trail on bikes, and to provide first aid — all while encouraging hikers on their way. People with first-aid or medical experience are especially needed as first-aid volunteers. First-time volunteers receive an ODH T-shirt and the eternal gratitude of the hikers. If you are interested in volunteering, please see [volunteering information](https://www.meetup.com/sierrapotomac/events/312467618/?isFirstPublish=true), or contact Mike Darzi (Mike.Darzi@Gmail.com).

It focuses on the heart, allowing individuals to connect with themselves on a deeper level, and ultimately achieve peace, relaxation, and clarity. It is a practice that encourages patience, self-compassion, and acceptance, helping cultivate a deeper appreciation for the present moment. This practice is offered with love and at no cost

Join us for a discussion of ***Cobalt Red: How the Blood of the Congo Powers Our Lives* by Siddharth Kara** Here's the summary: An unflinching investigation reveals the human rights abuses behind the Congo’s cobalt mining operation―and the moral implications that affect us all. Cobalt Red is the searing, first-ever exposé of the immense toll taken on the people and environment of the Democratic Republic of the Congo by cobalt mining, as told through the testimonies of the Congolese people themselves. Activist and researcher Siddharth Kara has traveled deep into cobalt territory to document the testimonies of the people living, working, and dying for cobalt. To uncover the truth about brutal mining practices, Kara investigated militia-controlled mining areas, traced the supply chain of child-mined cobalt from toxic pit to consumer-facing tech giants, and gathered shocking testimonies of people who endure immense suffering and even die mining cobalt. Cobalt is an essential component to every lithium-ion rechargeable battery made today, the batteries that power our smartphones, tablets, laptops, and electric vehicles. Roughly 75 percent of the world’s supply of cobalt is mined in the Congo, often by peasants and children in sub-human conditions. Billions of people in the world cannot conduct their daily lives without participating in a human rights and environmental catastrophe in the Congo. In this stark and crucial book, Kara argues that we must all care about what is happening in the Congo―because we are all implicated. **Let’s meet at Caboose Commons in Fairfax to enjoy some good discussion and meet new friends.**

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.

You have heard about AI. You know it can benefit your business. \- Can it save you time? \- Respond to customers faster? \- Allow you to take extra profits?
