Holy smokes you rack up the miles FAST! How many miles do you drive a day?
It's a crazy average combo of 60-mile round trip to work, 180-miles round trip to school ever day, same distance when you need something from a store other than the tiny grocery store at home, 240-miles round trip for any entertainment and real shopping like a mall or extra specialty stores. Add a few trips to Colorado at 800-is a round trip and one trip to Iowa.
I've always packed the miles on, where I live is so ridiculously rural you've got to travel for everything.
