Paintballing REALLY HURTS the next day -- not so much from the paintballs, which do hurt a lot, but the muscle strain. I mean, you're spending the day crouching down barriers, up and down on muscles you rarely use. Karting sounds cool -- I suppose shooting paintballs at passing gokarts could be fun, but it hardly feels like the Lexus thing to do. A nice picnic party is awlays great, with a few bands, lots of food, get somebody to run races and games for the kids. There's a great company called Charm & Happy, which has performers in every U.S. state -- you won't regret it.
