I have been to Yellowstone at least a dozen times so far. My wife and I are going back this summer to see it in more detail. We are planning a week long stay and still will not see it all. I will continue to visit the area at least every other year for the rest of my life. Living in Wisconsin gives us the advantage of being sort of central to everywhere we like to visit.
1000 miles to the Rockies
1000 miles to the east coast
1000 miles to New Orleans
We have been to the west coast and will not be going back. Sorry west coasters. We prefer the Rockies.
Alaska 4400 miles, this trip is in the planning.
