It's always good to break up a 9 hour drive, especially when you have 5 kids in a minivan.
We stopped at Coral Pink Sand Dunes State Park near Kanab, Utah
We took off our shoes and ran for the hills--vast, rose-colored mounds of the finest sand imaginable
Tumble down, race up, repeat.
As the only other tourist in the park observed, "Your kids are gonna be whooped for wherever you're going next." That was the plan!
We arrived in Phoenix right during rush hour.
