Same thing at my clubs. The new generation isn't interested in these types of competitions. They just want to hit a few tannerite boxes, post it on snap chat or whatever and go home.
I'm quite interested, the main issue for me is that some of these matches take so dang
long.
Some weekdays I'm out of the house for 14 hours at a time, so I basically need to do everything on the weekends. With a Saturday/Sunday match, that really condenses everything. Seems like whatever match I do, CMP, Steel Challenge, USPSA, it's more or less a day long commitment. Leave at 7:30 AM, get home around 3:30-4:30 PM.
That means everything--laundry, mowing the lawn, grocery shopping, etc.--needs to be done on one day when I'm either going to need energy for the next day (if Saturday) or going to work the next day (if Sunday). So doing all the chores Saturday leaves me a bit frantic on Sunday for the match or doing a Sunday match means being tired/sore on Monday.
If matches could sync up to like, 2 hours, 2.5 hours maybe, it makes it a lot more palatable. Something like getting up at 7:00-7:30 and home before lunch.
The last USPSA match I did I woke up at 6:30, was out of the house at 7:15 and didn't get home until almost 5 PM. Trying to do that more than once every 6 weeks or so is not practical for me. After May/June matches this year it just didn't work out with familiar commitments and whatnot.
As a side note some matches do the "welcoming" thing a lot better than others. I've been to some clubs/matches where it feels like you get the stink eye if you're not "one of good ol' boys" that's been there doing it for a decade. Some other clubs they do go out of their way to be helpful and encouraging to new shooters.
And lastly as a more personal issue these are a lot more fun with a friend. I think mac's mentioned similar issues before but I've had some people flake on me (as in, say they'd do a match and then cancel on me repeatedly). I've done several matches where I don't know anyone and it's not fun being the guy standing in the corner while everyone else chats, esp. if it's a 90° summer day and you've been in the sun for three hours...there's definitely some clique components to competing.
So I'd love to compete more, but ideally a Sat/Sun morning thing where I can go for more like a slightly extended range trip.
