Closest city or town to where you live that you haven't been to

[muon2]

It's a vague question since the definition of city and town varies by state. I'm going to restrict the list to the named urban core areas that make up the defined metropolitan and micropolitan statistical areas (the CBSAs from the US OMB).

By that measure the closest by time is Big Rapids MI at just under 4 hours. I've been in Mecosta county on US 131, but it doesn't go through Big Rapids.

Depends on your definition but I think it's Camaiore proper. There are a handful of closer places I haven't visited that are large enough to count but I've travelled through them many times and have probably stopped in all.

I have just visited Camaiore. Quite nice, although no different from all the cities nearby (except that it seems to have an unusual density of churches, all tiny ones). My new answer is more complicated but I am quite sure I have never even travelled through Pescia so let's go with that.
