Philadelphia. After this trip, it's my belief that going Iceland is always a good idea! Besides, I got a chance to catch up on the most recent episodes of Top Gear on the flight there and back.

I'd love to go back and this time rent an appropriate vehicle, ie, a proper 4x4. Good food, good beer, awesome landscapes, lots of hiking, some fantastic natural wonders, and reasonably friendly people. What else does one really need?
