I shot an email to the Brewers, even though the seller claims they are sold out. I asked if I can still get one if I register and donate. 2,750 seems like a LOT of people to donate at least $40. You're looking at $100 minimum, $125 if you do the half marathon. Fortunately I'm a runner so I'd enjoy the race, but I'd like to get the bobble if I can.
