I would say that maybe they spend it unwisely. The one episode I watched was about the guy in Arizona who just about blew his thumb off on a "practice shoot" with the boys (wasn't following the safety rules - you can't prepare for stupid). Anyway, this guy had at least four different caliber rifles (not including sidearms and shotguns) in his collection. I personally would just have two - .22 and either .308 or.30-06 plus a 12 gauge shotgun. You can get those anywhere. Too much diversity makes for complications. That was about as much as I remember. The blowing off the thumb thing pretty much blurred out the rest of the show. I haven't watched another episode since.
