We had a couple days to spend in San Francisco and luckily both the Giants and the A's were in town. Sunday we caught an afteroon Giants game at the new Pac Bell Park. It's right on the bay and a really great stadium.
We stayed in Oakland the night before and caught BART (the subway) over to San Francisco. We turned the wrong way from the station and had quite a walk. But we happened across some bike race. We may have seen Lance Armstrong, but we aren't sure.
Another note, it was weird walking on the Embarcadero street, since I've played many racing games and driven that road many times - and it looked the same.
