Travel much?
In the last 10 years I've driven over 700,000 months miles. About 100,000 a year, with two years off while I taught others to drive. This year I've been traveling about 2,300 miles a week so I'm on a 120,000 mile pace.
I've been to every state except Alaska and Hawai'i. I probably shouldn't count Maine, either, as I just spent a few minutes there and need to explore it more.
I fly when I must, but I'd rather set my own pace, stop to meet people, and see the sights and sites.
