Most likely hit the local spot early am and off the water by 11, or just hang out once the crazies show up. Maybe hit Grand. Have been there the last few years for mem day. Not great boarding, except early, but the coves are fun to cruise.
I'll be on Shasta. Oh but unlike the Delta it will be horribley rough, no place to board, cold water and the crowds, YIKES! Wont even be taking our boards with us its usually so bad. Id stay away from it all together if I didnt live here
