Today's Location: [San Francisco, CA]
The San Francisco graticule is at latitude 37, longitude -122. It completely encloses San Francisco, Oakland, and Berkeley down to the North part of of Santa Cruz, Scotts Valley, the entire peninsula, and a lot of ocean/bay. The graticule is about 60% water, making reachable geohashes a little sparser than normal. If today's San Francisco geohash is in the water, you may find the San Jose geohash more to your liking. In addition, there is a large amount of private property in the hills of our graticule, although also a lot of public land and terrific parks/hiking, so it should be interesting hashing, when we can get there. On days when the spot is off-shore but within 1 mile, or in The Bay, Ted suggests that we try to make it, anyway (boats, wind-surfers, whatever), if it can be done, safely.
The San Jose, CA and San Francisco, CA graticules share a mailing list for meetup planning and other discussion.
Interesting fact: 37, -122 is the graticule used in the original Geohashing comic.

alphabetized by You, when you add yourself, please, keep it in alphabetical order.
- Aaron - San Francisco. Have car, bike, and hand-held gps (with maps). Works a desk job but might be up for weekend adventures occasionally (or underwater speed chess).
- Ana - Palo Alto area. No car, but might be able to get a ride if sibling can be persuaded and we have time.
- Annie - Menlo Park area. Have an RV, usable as normal vehicle, and able to go during day.
- Anthony - Alameda, CA. Has car, but not much ability to coordinate schedules with others. May attempt locations after work
- Avitzur - Berkeley.
- Benbald72 - Berkeley, do not have a car but is resourceful with public transportation and would be willing to meet up to get a ride.
- CipherSwarm - SF. Has car, road bike. Sticks to SF graticule.
- Darcy - Berkeley. Has a car but may often be busy. Needs to figure out if her driving GPS can be configured for off-road hashing.
- EntropyRulesOk East Bay.
- Evawings - Somewhere in the Redwood City/San Mateo area. Likes random adventures! :]
- Erik - Stanford student. Just a bike so I can't go far, but I try when I can!
- Filip - San Francisco native, watching out for in-city points and interesting ones elsewhere. Muni ninja. Added peeron page to bit.ly/Geosf as an alternate shortcut, but be careful, it's case-sensitive! (All-lowercase was already taken.)
- FunkyTuba - Cupertino/Redwood City. Will probably only go to *very* convenient geohashes, e.g. the point falls within a couple of miles of home or work.
- GrapeFruit - Campbell. Technically San Jose Graticle,but as others have noted, SF will often be more interesting/doable.
- hellmitre - Has car with room, will travel. Could it be possible to decide on a certain Saturday so we get a good number of people to show?
- Jakobo - San Jose, but often the SF spot is a cleaner run up 680
- Jestelle - San Francisco, CA. Bikable locations from the city are what I'm waiting for... I created geosf.shorturl.com for easy URL remembering.
- JohnthePawn - San Jose, have a car and am willing to go hash into park and forest area should time permit.
- kachunk - Palo Alto. Has car. Prefers to bike.
- Mystitat - Walnut Creek. Has car sometimes, but prefers public transit.
- Nate3000 - San Rafael, CA. Will have car soon.
- Pwnagepanda - Piedmont. Has car/bike, will hike. If it's near my area I'll try to make it
- Pyron Beta - Sunnyvale. I've suggested using DJIA==0 so we can find a Friday with reachable coordinates.
- Quertior lives in Santa Cruz, but his house is located in the Salinas graticule. Unfortunately, neither of those two are very active.
- Relsqui - Berkeley. Has transit passes, will travel, within the bounds of public transit and a full-time job that includes Saturdays.
- Ted - Santa Cruz. will bring Once Upon A Time when he comes. He will try to make Saturdays and, in particular, suggests the 2nd Saturday of the month for folks who plan to only attend occasionally. (Perhaps that can be "the official SF-xkcd meetup", or some such.)
- Treiza - El Cerrito, CA. Has car and bike. Willing to give rides.
- Tuzakey - Walnut Creek, CA. Has car and mountain bike, will travel if motivated.
- You - lives in San Jose, but the SF is often closer.
- Youhas - Technically in the San Jose graticule, but close enough to the graticule border to visit the San Francisco hashes when San Jose proves distant / inconvenient / disinteresting. (Doubly so when the SF spot is in the Santa Cruz mountains - my childhood tromping grounds!)
- Zigdon - Santa Clara, will try to drive or ride to meetups if they are close enough. If the meetup falls in the sea, the San Jose graticule is often a good alternative.
