You don't need a full rack just take a set of draws, rope, and a couple lockers for your anchors. There's some bouldering in Mission Gorge and you might get a blay from a local but note they can be unfriendly on occasion.
Obcessed is what lazy people call those of us who are dedicated!
well I didn't make it to any crags while I was out there, but I did pass Solid Rock Gym on my way across the border to Tiajuana. It looks quite small from the outside, around or under 30ft. is my guess.
