I'll admit that I'm doing a lot more bowling than shooting these days and a lot of it has to do with economics (and another big part is family-oriented). I bowl in two weekly leagues and practice twice per week. All told, that costs me about $60 per week for approximately 10 hours of active participation, and at least half of that is actual sanctioned competition.
At $7 for 25 targets and $5 per box of shells, that same $60 might get me an hour of active participation at the gun club and that's sans any real competition, as the local club doesn't offer any.
If I drive to Phoenix to bowl in a tournament, which I do every other month or so, I'll pay an entry fee of around $55, which ensures at least six qualifying games. If I go down there for an ATA shoot, I'll spend that for every sub-event (shells included).
On top of that, my wife and 12-year-old daughter will bowl with me fairly often (my kid, although not really obsessed with the game, has finished 2nd and 3rd in the state the last 2 years for 12-and-under girls). I've gotten my wife to shoot at 4 clay targets in the 23 years we've been together and my daughter is still unwilling to try it.
I'll keep my hand in trapshooting for the foreseeable future, going to the club once a month or so, but I'm no longer immersed in it, and it'll stay that way for the time being.
