Chelsea proving grounds

It's alive and well, hill is still there, they use that mostly for testing the pulling power of the Ram trucks.

I live 15 - 20 minutes from there, and have several friends who work there.

Nice big junk yard right out by the road with a large berm around it from all of the cars they wreck, hitting deer, rolling them, what ever floats their boat at the time. If you look just right you can see them for just a second when driving past.
