Where’s A Good Place To Teach Your Kid To Drive? [POLL]

My 15 year old son recently bought an old Chevy pickup for his first vehicle. Considering he has about 10 months left until he takes his Drivers License test, he has plenty of time to figure out how to drive a stick. I've been taking him to random empty parking lots so he can learn, and yesterday, we spent about an hour at the Casper Events Center. He's actually doing quite well (don't tell him I said that), but I'm wondering where I'm going to take him to get some actual real driving experience...without having to worry about slamming into other drivers.

Driving stick is obviously more involved than automatic. With all of the hills we have around here, he's going to need to get used to starting at an incline, with a car right on his bumper. Where would you suggest? Look through the options below, and if you can think of somewhere better, add it! We'll post the results tomorrow.
