I didn't go, but I thought this was a nice gesture for those of you that stuck it out. From John Shea's article in the chronicle:

"Goodwill gesture: Rain-soaked fans who attended Tuesday's game can get free field-level tickets to a future Monday-through-Thursday game, excluding July 2-4 (Red Sox) and July 19 (Yankees), by bringing the ticket stub to ticket services at the Coliseum."
