**IMPORTANT - READ** Monongahela National Forest limits groups to 10 people, so that is a hard limit for this trip. If you are not 100% committed please do ***NOT RSVP*** ## **Trail Facts** * **Difficulty Level: Moderate** * **Length:** 16 Miles * **Duration:** 2 Days * **Elevation Gain:** 2,216 Feet * **Bear Canisters:** Not Required * **Permits:** Not Required * **Parking:** Red Creek Trailhead * **Coordinates:** 38.972729, -79.397824 * **AllTrails Map**: [https://www.alltrails.com/explore/map/dolly-sods-backpack-16-mi-24357dd](https://www.alltrails.com/explore/map/dolly-sods-backpack-16-mi-24357dd) The Dolly Sods Wilderness is a U.S. Wilderness Area in the Allegheny Mountains of eastern West Virginia and is part of the Monongahela National Forest (MNF) and one of the most desirable trekking areas in the US. Dolly Sods is a rocky, high-altitude plateau with sweeping vistas and flora and fauna normally found much further north in Canada. A backpacking trip in this area will expose you to a very diverse and unique landscape with sphagnum bogs, grassy meadows lined by spruce trees, wind-carved boulders, and beautiful mountain vistas. Note - this area can have very unpredictable weather. I've had everything from sunshine, to heavy rain, to even snow and hail as late as May. Pack accordingly. **Trail Details:** We will meet at The Vienna Metro station on Saturday morning at 8am and drive to the Red Creek Trailhead at the southern end of the Dolly Sods wilderness. The drive is about 3 hours - I will drive and am happy to have up to 3 others carpool with me. When we arrive at the trailhead, we will hike about 6.3 miles to our campsite, stopping once to check out the the iconic Lion's Head on Breathed Mountain (pictured in the post). Should be an early day, so feel free to bring cards, adult beverages, or other items to pass the time. The second day, we will explore the rest of the park, which includes the rugged Dunkenbarger trail. The second day is about 9.4 miles back to the car. There are a ton of stream crossings on this trip - so expect to get wet and pack accordingly. **Essential Items**: * Tent * Sleeping pad​ * Sleeping bag suitable for expected temperatures​ * Backpack (appropriate for overnight backpacking)​ * Backpacking stove with fuel​ * Pot, cup, dish, and utensils​ * Dehydrated meals​ and snacks * Water bottles or hydration system (capacity for at least 2 liters)​ * Water filter or purification tablets​ * Headlamp with extra batteries​ * Rain gear * Dry bags or pack cover​ * Warm clothing layers (non-cotton) * Trowel for and toiletries for Leave No Trace compliance **Optional Items**: * Personal first aid kit​ * Map and compass or GPS device * Power bank or external battery * Trekking poles​ * Camp shoes * Electrolyte supplements​ * Alcohol​ * Books, games, or other enterainment * Gaiters​ * Sunscreen, lip balm, insect repellent​​ **General meetup location:** Vienna Metro Station - 8:00am Time driving: 3 hr. each way Google driving direction from Vienna metro: [https://maps.app.goo.gl/KUW283UFEe5kJJnLA](https://maps.app.goo.gl/KUW283UFEe5kJJnLA) **CARPOOL:** Don't forget if you want a ride or are willing to offer a ride – be a friend to the environment, save money, and make friends. **LIABILITY NOTICE:** Please remember that this group operates under the common adventurer model.

NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it.

New players are always welcome to come try it out! What you need: A bathing suit. Preferably something light and tight. We have extra gear for new players. But if you have your own pair of flippers, a snorkeling mask, and a snorkel then bring them along. Please bring this signed and completed form to practice: https://cdn1.sportngin.com/attachments/document/c7dc-2321473/USOA_Waiver_2022-07-07.pdf Unless you are already a member of USOA: https://www.underwater-society.org/page/show/4284471-usoa-registration To find us: You can tell the front desk that you are here for underwater hockey and they will let you in for free. You can ask them for help finding the pool. If no one is at the front desk just walk past it and there will be a set of stairs on the left. Take the stairs and take a right at the bottom of the stairs. The men's and women's locker rooms are straight ahead, and you will need to go through them to access the pool deck. Once you are out on the pool deck you will be exactly where we practice. Agenda: First 15 minutes: Arrival at the pool, getting gear from the shared gear bin, dividing into two teams, getting gear on. Minutes 15-30: Getting in the water, teaching any new players the basics Minutes 20-70: Scrimmage/practice. Minutes 70-75: Putting away club gear, putting the lane lines back in place, clearing the pool deck. (optional) afterwards: Go to a local restaurant for food, drinks, and socializing.

Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects.
