Road trip planning – ideas welcome

We started our spring road trip planning today.  Tentatively planning on a mid-april departure for about a month and a half.  We still have yet to visit many of the states, so tons of things to check out.  Currently thinking we will start heading west to Arizona, then north to Wyoming, then back east and south to Florida.  Laying out ideas of places and people to visit, hopefully camping most of the time.  Still deciding on whether to buy a travel trailer for this trip…

If you have any thoughts on places to see along the route, let us know!
