Assuming you could drive over oceans

Work has been under way on Corridor X, the $1 billion interstate that eventually will connect Birmingham to Memphis, for 22 years. If you had driven at 50 mph for eight hours every weekday for 50 weeks a year from 1983 until the time the whole thing is finally done (2011 at the earliest), you could have circled the equator roughly 112 times.

But you wouldn't have seen Tupelo even once.
