The perfect American city would have Dunkin’ Donuts and Jamba Juice franchises on alternating street corners.
Alas, I know of no such city. According to the Dunkin’ Donuts Store Finder, San Diego is *right out*. And according to Where’s Jamba?, there is only one store within 99 miles of Boston. Interestingly enough, this store is about a half-mile from my grandmother’s house in North Cambridge. So while Greater Boston wins hands down over San Diego in the beverage department, it’s still woefully short on Extropian blenders.
