I just spent a couple of weeks in Myrtle Beach South Carolina and during that time I didn't see a single maxi scooter of any description! There were lots of smaller scooters however.
I am still in shock of this because coming from the "frozen north" I expected to see them everywhere. They have the perfect climate for scootering all year round. Another thing that adds to this surprise is that I went into a very large dealership and the first thing you saw when you entered was a large display of scooters. At least they're trying.
This is definitely Harley country.
