Twice a year, the gun range outside of Fort Knox (West Point, Kentucky) hosts a machine gun shoot. All of these Class 2 and 3 firearms are legal and licensed.
I've talked about going for several years. But this year, I may make the trip. The racing scene in the U.S. is becoming rather bland (NASCARized), IMO. Until I get the time (and money) to go racing more than once or twice a year, maybe I should get a Class 3 weapon and go play a few times a year... with Yosemite Sam types at least as crazy as I am.
