Favorite cities and states for RVing?

My favorite cities are the ones I can bypass. State wise is a little tougher, although Colorado would rate at or very near the top. Likewise any of the western mountain states from Washington down through Utah. If I took the time to travel the eastern states along the Appalachians I’m sure I could add to the list. But I’ve found interesting places everywhere I’ve traveled. At the beginning of the year I traveled the south to Florida and into southern South Carolina and it was a fun trip. But flat land holds little attraction for me and can't hold my interest for long.
