Hi. Been thinking about doing the Grand Circlr Road Trip in 2014. I was wondering though if it could be national park overkill. I don't want to sound negative but Zion, Bryce, Arches, Capital Reef, Canyonlands ect all look similar. I know there are things in some parks that are not found anywhere else and are unique to that park but the landscape does look very much the same. Is my concern justified?
