BBRSP!
BBRSP is quite possibly our favorite park in Texas. The draw is that there is far fewer foot traffic than BBNP - so much solitute. We camped at Fresno Vista and backpacked the Rincon Loop from the Barton Warnock Station... about 30 miles in 3days/2nights. Wifi at the Ranger stations and a shower at the Sauceda Station. If you have any questions don't hesitate to call the Ranger stations. Water near the Crawford Smith house.
