Freestate's air system is ok. On Target's is better, but the downside is sometimes the targets dance around due to the air blowing. I don't know, maybe they fixed that problem. I don't go there anymore because Freestate is closer.

Pay attention when you hear about the EPA or some other group wanting to ban lead bullets and lead sinkers. Their science is suspect and has been for some time. Back in the '80s, the government had a study conducted at Gettysburg due to worries about how much lead was in the soil. The study found that once lead oxidizes, it does not leach into the soil or water. The antis never want to talk about this study however.
Freestate's ventilation is pretty damn good-- blows fresh air from the front of the firing line to the back of the target area where it is ventilated out... Sometimes the targets do dance a little inside of 5 yards if you just have a large paper hanging target, but if it does, just ask them for a piece of cardboard to stiffen it up--- they'll gladly give it to you no questions asked
