NO!!!!
i am not gonna be here!!!
oysters..easy. hit highway one. i like Tomales Bay oyster company.
no check that. you could go to Bodega Bay oyster company. (i was there Saturday - $55 per 50)
buy a bag..they have free ice, but you will need an ice chest or something..
then go to Gleason Beach on Hwy 1..there are some park benches i NEVER seen used. you are right next to the rocks, and beach.
OR..you could do Tomales Bay oyster company..they dont allow picnicing anymore since the neighbors *****ed. but they have great product. you could find a beach bench north or south pretty easy. they make you buy ice.
BEER. definately go to russian river..downtown Santa Rosa. my hood!! they are supposed to open there new location soon..in Oct. it will be great. my fav IPA is Blind Pig..in case youre interested.

Laguinitas is getting pretty huge. but they do have a great vibe still.
i wish i was here when you were here!! i would blitzkrieg your liver.
