Free Money Making Idea

During yesterday's extremely infrequent visit to the local Carvel, I noticed the server wearing a "Cape May" sweatshirt. 
I had the thought: I bet if you went to Cape May, the server at the ice cream store would be wearing a sweatshirt that said "Nantucket", or "Kona" or "Aspen", or "Cabo" or anywhere but Cape May.
I haven't been to Kathmandu, but I'll wager the kids there wear "Jackson Hole" sweatshirts more than they wear Kathmandu sweatshirts.
So here's an idea for Sweatshirt Makers:
print sweatshirts that say:
"Some Cool Place, other Than Here"
it could be a World Wide Bestseller
