Stratcat... I have been to the range also. They throw a hell of a 4th of July party with some nutty pyrotechnics blowing stuff up.
They have 2 hand gun ranges, a high power rifle range, traps, and my fav, the plinking hole. People throw stuff in the hole(garbage can lids, whasher/dryer, GAS CANS lol)and shoot it up with thier fully auto guns. Some of the people scare me when they mount thier 50cal to thier truck wearing full camo at the range. I was told if it doesnt explode on impact, its OK. I havent been shooting in about 5 years so this may of changed. Here that site.
