I have been going to Blue Trail for as long as I can remember. Way back when, I was one of those 10 year old kids shooting bolt action .22 prone on the floor of that very same indoor range every Saturday morning. I basically grew up shooting there.
I mainly goto Blue Trail for 100yd. centerfire rifle. But if it's a cold day you will freeze your ass off on the line, so I haven't done that in a while. But if you think it's dead there and no one ever goes outside, think again, you should have seen it the day after Thanksgiving last year it was a mad house!
However, your criticism of the indoor range is accurate. Besides it being strictly .22 ONLY, it doesn't have any distance markers and it is not too well lit. It also probably hasn't been renovated since like the 50's. I still go there often with my Buckmark when I have to scratch the itch to shoot something, and it is good for that.
The only thing that gripes me is I feel I really annoy some of the older "target" shooting crowd with the custom .22 rifles that frequent there. I am standing there shooting box after box of .22 and the other guys are taking about 1 shot every half-hour and over analyzing it to no end. To each his own, but I am a paying customer just like those guys... so I ignore them and there sometimes nasty looks and just do what I want. :)
Lenny, the NRA instructor at BT, is a really nice guy. I took my pistol permit class through them and you can tell this man has incredible wisdom and knowledge about shooting. When he speaks, I always listen up good. I believe Mike was the mans name who I bought my Buckmark from in their little range shop, another very nice guy who I recieved excellent service from. The women who takes the money for the range tickets is a little indifferent, but not impolite. Imagine how boring her job must be though... so I don't hold it against her.
All in all, I grew up going to Blue Trail and have some very fond memories of it. It is almost like a second home to me. :)
