Been there done all those too Vet. Not impressed with any at this point. Nashville was not bad when I was a child visiting there, but the rest are not on my favored list. Just give me a mountain retreat for the best kind of vacation. I hate cities and only go to Columbus now because I have business there on occasion. Get in and out as fast as possible.
If you ever get to Omaha you HAVE to visit the zoo. One of the best in the world.
