Walking?

Went by a large-ish lady giving some poor unsuspecting tourists an earful earlier. The funny thing was... well:

Lady: ...Everybody walks, there's only one ATM, only one gas station - Its a rural artist's colony.

You don't see what's so funny? She had her back to the main highway in town (it and some of its offshoots are THE! ONLY! PAVED! ROADS!), and occasionally had to talk loudly to be louder than the steady trickle of cars and trucks passing by.
