Wait, there are states that DON'T do the mile marker thing?
I think only in some states in the northeast where the old systems are grandfathered in...I'm pretty sure the latest highway standards are to have exits=mile markers. I-89 in Vermont and I-93 in NH used to be simple numerical order (so exit 13 could've been 20 miles after exit 12) when I was in college, but I think they've both switched to the standard system long ago.
