Bay area crags that dry fast after rain?

I'm hoping to go climbing this weekend, but not quite sure where to go that would be dry.  Since most crags near the Bay are a good distance away in shitty traffic, it would be nice to go somewhere that I know will dry quickly.

This Sunday looks like great weather, but I'm worried about seepage.  I was thinking about going to the Grotto at Table Mountain- is this a good idea?  I feel like Mt. Diablo and Castle Mountain are probably not a good idea to climb on after rain.  How about Pinnacles?

Pinnacles has some good climbing, but it's also a choss factory...and that's when it's dry. Three days per day of rain minimum

Howdy Mark! The Bear at Mt. St. Helena is a pretty good choice if it is sunny out since it gets a fair amount of direct sun and doesn't have much above to seep, but it looks like it will probably be rainy/cloudy there. The Grotto could be hit or miss as it doesn't get much rain due to the roof, but also doesn't get much sun because it is in a depression; I would think Gold Wall might be a nice option though because of the direct sun. Cosumnes River Gorge also gets a lot of direct sun, and the smaller formations there don't have much above to seep.

Pinnacles is definitely a no-go, as is Castle Rock and Mt. Diablo.

East/ Indian rock dries out pretty quickly.

I've climbed at Pinnacles many times the day after a rain.  Usually it's fine.

It is not as fragile as the small-grained sandstone at Castle Rock and Mt. Diablo, where the 3-day rule to dry out really applies.

The Bear is NO after heavy rain. A long explanation of local geology could ensue but it's no, let it dry.

I'd be interested to hear more about geology.  Just the Bear, or the rest of Mt. St. Helena too?

Gold Wall is looking like the best option right now, I think.

By the way, Clint, I probably spent 100+ hours in high school reading through your Index topos and getting psyched.  Just wanted to thank you for making those available!
