East Bay - Indian Rock/ Mortar Rock

Going to be in the area from Aug 27th-Aug 30th. One of those days I'll definitely be at Dogpatch Boulders and another I'd like to hit up one of those crags. Is there any one available to meet up? Or would I be able to bum a crash pad or two? I'm sure I'll run into some climbers, but I thought I'd ask. I can repay in beer or food, or some cash if you prefer. Thanks!
