He blogs, he codes, he works for LinkedIn. I hear they do professional networking stuff. He fell first into geocaching, then into geohashing, though they happened about the same time.
He lives in Mountain View, right near Castro St and the Caltrain.
He loves shiny things.

2008-06-15, San Jose - Arroyo Hondu Road is not accessible. Or so I learned. Marsh just kinda ends. Did get a few photos while out geocaching in the area though http://flickr.com/photos/jakobo/sets/72157605649769963/. There's got to be a way to the East side of the Calaveras Reservoir, though I have yet to find it.
2008-06-22, San Francisco - While not accessible, the beach it was near was awesome. http://flickr.com/photos/jakobo/sets/72157605771363560/ Also met up with CipherSwarm. Close though, so very close.
