I am considering a three day biking/hiking/camping trip to Caprock Canyon state park in Texas. First week in May possibly. Palo Duro canyon state park is just a few miles more, and I was wondering if anyone knew which one would offer better red rock oportunities? Anyone ever visit either of these areas?

For those not familar with these areas:

Thanks in advance.
