Good idea.  Have noobs test fire markers, have demonstrations of real games, field tour, do a noob 3 on 3 or 4 on 4 paired with unarmed paintball veteran escorts/guides/coaches, demo of semi-pro vs. semi pro game, demo low budget gear, hi-end gear and just show all the fun people can have young and old.

Hell, I'm still a noob.  But I now know you all aren't a bunch of militia psychos.  The game is fun.  I didn't know how fun til I did it, especially at Field 51.
