ATX14 - Yes we made the trip. Had 9 Jeeps in the caravan and had a blast.
Black Gap is now just another Sunday drive in the National Park. Stock jeep and stock tires will have no difficulty.
State park is a real blast. Visited the Solitario, drove the Road to Nowhere. Best of all was a short 4 mile trail that took over 4 hours. The state park is a definite bucket list item.
