The coolest thing is that it was in a room with a basketball court, so it was *huge*. We took the stomp-rocket thing and launched Nerf arrows up into the top row of bleachers and threw them back and forth and stuff for about an hour. It's neat being able to fire a nerf dart across an entire basketball court in one go.
Played a couple of games of Unexploded Cow, too. Cheapass Games rocks.
