For participation. What?! Is this Tee-ball? Peewee soccer? The Special Olympics? No, wait, it's Pro Division tournament paintball. Okay, I hear you. The NPPL guys probably never thought of their nice plaques in those terms and almost certainly didn't mean to suggest that everybody should be proud, and, erm, happy just to participate--but good grief, read the plaque!
By the way, the back is almost as good. It says (and I quote) 'Provided by Arrowhead Wood Inc. The official furniture sponsor of the NPPL World Championships in Las Vegas.' What a hoot.
