I've hit most of the SF/Eastbay places the last couple of weeks:
Cards and Comics Central: Not sure if the above poster is from the store or just plays at it, but the last two times I went to their bi-weekly constructed WoW event, I was the *only* person there. They have basically 0 wow singles to sell. Ultimately, unless something has changed, seemed dead.
Eudamonia: Draft on tuesday usually gets a good number, but crowds have been dying recently. Went from a consistent 8-10 to 4-5 the last 2-3 weeks. Summer is driving everyone away!
Games of Berkeley: Draft on thursday officially dead I believe. Stopped in 3 weeks in a row with no more than 1-2 people there.
