FWIW, my son informed me last weekend that he signed up to officiate intramural basketball games this spring after his college season is finished. (probably not a good idea, but I appreciate him wanting to make a little extra spending money!). He told me he'd like to get together one day and let me give him and a couple of buddies a few tips to get started.
I told him he would need a whistle with a pea in it, a shirt with a collar, a duffel bag, and to be sure to come to the game already in uniform.
I figure that way he doesn't have anyway to go but up!
