I was up in San Francisco for work this weekend and was staying in Alameda so I decided to see the Giants game Friday night. I caught the ferry across, which worked out perfectly, no parking issues, no traffic problems at all! The game was good (but the Giants lost in the 10th) and the park was awesome, but chilly! I also met some really awesome people waiting for the ferry back.
I have two stadiums left for this year (Dodger Stadium and Angel Stadium). I am going to the Angels game on the 31st and the Dodgers game September 22nd, which will complete my West Coast stadiums for the year.
I'll still catch a few more Padres games this season and I'll be up in SF again in September so I plan on getting to a few more games in Oakland as well.
