US 421. “The Snake”. 37 miles and 489 turns. Never heard of it and just realized it is 10 mins from my house here in Bristol TN. Lived here 2 years now. Such a fun road!!
They are good. I figured they use them in car dealerships and the same thing in the Army Basic Training Barracks. If they can hold up to that, they can hold up to what I am doing.
Only about 500 bucks to do the whole garage.
