There are hundreds of "parks" in Utah, the trick to beat the crowds is,,,,,don't go where the crowds go. Utah is a large area with many secondary roads throughout the state that will take you around the edges of the national and state parks, and some of the more scenic areas I might add. We and friends are leaving on wed. to do just that for a four day trip during the MIDDLE of the week up through the west center of the state and back around and down through the east center to return home to Cedar City, no reservations needed.>>>Dan
