Haha, I live just over an hour from Yellowstone and avoid it like the plague.
I went on a trip a few hours north of Yellowknife, NWT. The road ends at Yellowknife, so we went out in a little 6-person plane and landed on the water at a hunting camp and fished and looked around for caribou for a week. I'm a big fan of places without much life, so that area was the shit. The next closest thing for me would be the Beartooth Plateau in SW Montana.
