 Local Geohashers
- Anna lives in Bethesda, not far from the intersection of four graticules (Baltimore, Frederick, DC East and DC West) and would like to attend on Saturdays in whichever graticule presents a closer/more interesting location. However, she is a little discouraged by the seeming lack of recent activity on this page. Is anyone still here? Did the Halloween meetup ever happen?
- Bree lives in NoVa, and plans to attend meetups simply because adventure is too good to pass up, and her mom will freak when she finds out.
- Thomas lives in this area, and plans to attend the meetup in whichever local graticule is most convenient on Saturday.
- Colin also is a resident of this area and plans to attend on Saturday (May 24).
- Steve and Lynette currently live in the Eastern Washington graticule, but are moving to the Western in two weeks, and will attend whichever meetup is most convenient whenever they are able.
- Dan technically lives in the very bottom of the Frederick graticule, but will be attending meetups in this graticule when it's more convenient (gas is expensive!).
- Brian's mother has a house on Kent Island, which would be ideal to visit on a day like today
- Justin also lives in the Fairfax area, and will attend when able - like Dan said, gas is expensive!
- Alex is a college student home from the summer who got turned onto this geohashing by a friend in Portland OR. She hopes to participate in as many geohashes as she can before she leaves for Santiago Chile in mid-July.
- Alex H. is looking to do some geohashes with his junky old GPS unit in Alexandria.
- Phil is in the Vienna area.
- EpeeGnome has been out of the loop for over a year, but would like to get involved again if people are still going to these.
- Katie lives in the Baltimore graticule, but will be attending meet-ups in the DC area as well when convenient.
- Scott I'm in Arlington, and will come to northern locations in both graticules. May do farther out ones if they fall in a park/public space.

 Notable Locations
2008-05-22 ~ Awesome, it's at someone's house, looks like quite a big house too
2008-07-11 ~ A very accessible location, just a few feet off of the road - accessible, that is, if you have access to Quantico!
2008-07-17 ~ On the ramp to the East Falls Church metro. Anyone who rode the Orange Line from points west passed right under this spot. Potentially thousands of unwitting hashers!
2008-10-19 ~ Inside the I-95/VA-234 interchange in Dumfries.
2009-01-13 ~ On John's way to work. Too bad he didn't notice until he got home.
2010-07-15 ~ Directly over Eastbound US 50/301, between Bowie and Annapolis

 Recently Visited Locations
2012-2-04 Custom Designed first hash, in Quinn park (part of Mannass battlefield park - some stone walls remaining from houses involved in the battle). Was easy, park road takes you to within 100', and the spot is across a small creek. No trespassing issues, park is open to the public until dark. Unfortunately, it was so easy, that I didn't go right away, and was too busy doing open source software releases to remember until after 4pm. I was 45 minutes late.
2010-2-27 Fitzy's first attempted Hash, in the middle of a farm field near Warrenton. After winning an epic battle with some mud for the ownership of his shoe, he was decided to give up a mere 500 ft from the hash point when he heard gunfire nearby (like, REALLY nearby).
2009-10-22 DC West. Aw, this sucks: I am at this location probably twice a week, but I can't get there today. Where is it? It's at the New York Ave Metro station! Really, right at the station! Man.... --Tom
- Thomcat attempted a retrohash on 2012-06-07 and confirms the parking lot is still under construction.
2009-01-31 - Official Saturday Meetup DC West Chuckrex attempted, with two drag-alongs. We got close, I think, but suffered GPS failure and couldn't reach hash. One of drag-alongs was 4 years old, so couldn't spend much time solving problem. FAIL.
2009-01-10 - Official Saturday Meetup DC West- The location for the Saturday meet-up was very close, right in the Metro area - off Rt. 50. Unfortunately, perhaps due to the near-freezing rain, only one person - Chuckrex - showed up. Noticed at least 7 "no trespassing" signs on turning into the parking lot of the property, so didn't stray any closer to the actual spot. But got some nice photos of their signage defenses.
2008-09-13 - Official Saturday Meetup - On a canal-side trail behind some apartment buildings. EpeeGnome showed up 3o minutes late and met no one. (1 attendee)
2008-07-12 - Official Saturday Meetup DC West. At a driveway in the Woodbridge area, about an eight mile drive from the last meetup 2 weeks earlier. (5 attendees)
2008-06-28 - Official Saturday Meetup DC West. Successful geohash and meetup. In a patch of woods between a gas station and a subdivision. (6 attendees)
2008-06-20 In the parking lot of Giant/CVS Pharmacy at the corner of Gallows Rd and Rt. 50. good shot- just east of the truck parked perpendicular to the parking lines (1 attendee)
2008-06-14 Official Saturday Meetup - Very close to the water in Founder's Park. Just off the Braddock Road Metro rail stop. (16 attendees)
2008-06-07 The point was in the woods near an abandoned house west of La Plata, Maryland. (1 attendee)
2008-05-25 - A promising location at a private residence in McLean. (Interesting fact: you are about 1000ft from the headquarters of the world's largest candy company (Mars Inc), yet probably never realized it. Their headquarters is an unmarked 2-story brick building on Elm St.) (1 attemptee)
