At SBC Park, the Giants shoot off some sort of steam from three stacks by the right field arcade (overlooking McCovey Cove), and a foghorn goes off. Also, a cable car bell is rung. That's really cool. And we cheer. :-)
PacBell Park is now SBC Park? These corporate names drive me crazy, plus many of them keep changing!
PacBell/SBC Park is probably the #1 ballpark hubby and I would love to see next... it looks beautiful on TV. We've been to Candlestick (can't remember its corporate name) and Oakland/McAfee Coliseum back in the early-to-mid 90s when we used to spend a fair amount of time in the Bay Area. Hubby actually used to work at Oakland Coliseum back in the 70s, although he grew up a SF Giants fan (Willy Mays!).
