How about a day out at a minor league baseball game?

Of the 2 above, I think the Blue Claws would be a better option. The parking is MUCH better than Trenton, and I think they might let us display the cars out in front of the main entrance before the game (I remember a bunch of riced-out scions out front before one of the games this year).
I think the blood drive is an awesome idea, too.
