Indoor range at Shoot Straight there in Tampa is 100 yards with two lanes. It's not air conditioned, but the have a nice exhaust fan system so you're getting a pretty good percentage of fresh air. I've been there a few times and even when it's pretty hot outside, it's not oppressive.
You're going to enjoy the place, Quaker.
And Wyoming Antelope has some longer range set-ups,but they have a large number of pistol ranges, too. It's all outdoors, and for a long time they wouldn't let you load a magazine in your rifle. You had to shoot one at a time, reloading each time. I think that's changed, now. With a yearly membership, shooting was reasonable, but as a guest, it's something like $20. FWIW
The real longrange set-up in this area is at the Manatee Rifle and Archery Club--they have a 1000 yard range with a big steel gong at the far end so you can tell when you've hit it. I've never heard the gong on any of my trips.
