UPDATE #2: I think North Carolina was very interesting, for the food. I've had both really good food experiences there and really bad. The really good food was a vegetarian meal at, of all places, a traditional meaty BBQ. I had side dish after side dish and it was totally amazing.
The really bad food was at a wedding; they served us paper cups of kool-aid and dried out tiny cakes. Eeew.
Where have you traveled? What was the most interesting place you visited, and why?
UPDATE #1: A friend of mine who flies his own small plane shared this with me. I think this is a great way to see the world. He's flown as far north as Nashua, NH and Ra-ra-ra-Rochester, and as far south as Ocean City, MD. I wonder what Nashua, NH is like? According to Wikipedia it's the second largest city in the state.
