Mayberry AKA Mount Airy

Mount Airy is the birthplace of Andy Griffith, they like to bill themselves and the "real" Mayberry. 

The show wasn't filmed there, there is nothing "authentic" there except Andy Griffith's birth home, which you can rent out to stay in for your vacation.  (I would really like to meet people that choose to stay in Andy Griffith's house for their honeymoon, I think they would be very nice people.)  There is an Andy Griffith Museum, and a Andy Griffith playhouse.  Other than that, things are rather opportunistic. 

You have a barbershop, why not name it Floyd's?

Or build a garage the looks like Goober Pyle's...

 And while you are at it build a courthouse next door...

Then you can get some old cars and paint them up like patrol cars and give people tours. 

It was fun to drive through the town and see the sites, for us, for our kids, they only vaguely knew what we were talking about.  It makes me wonder how much longer will even this tenuous fame mean anything.
