I just moved back to San Francisco, and I usually have weekends off (assuming its friday-sunday).
I don't have a car, so I can only get as far as the BART allows, but I can pitch in gas money if anybody wants to carpool!
I've been wanting to do something more rigorous than what I've been doing (about 15mi per day on backpacking trips) or something along that mileage would be great as well. I'm really down for anything.
What were you thinking of hiking?
