That would create a few "problems" durring a game.I hope that never happens.
But OTOH, IMHO if there is gonna be an earthquake in SF, I would rather see a 20ft wide fault split the left side of the batters box at Pac Bell Park's first home game of the 2006 season durring Barry Bonds first at bat.
....OK,....after rethinking it. I really WOULDN'T want a 20 ft wide fault split......Make it 30FT so Barry's head and ego will fit in it.....
