What's the farthest you've ever walked? (More or less, at once, and treadmills don't count. And I'm not talking about jogging, because usually the intention is much different in that case.)
My guess is that if you've ever walked many, many miles, there's probably a pretty cool story behind it.
My longest walks have probably only been 10 miles or so, through a nature path, hiking trail, or in the country outside of town. The memories of those experiences didn't have much to do with the distance covered, though.
How about you?
