Unfortunately, no. I looked into this a while back and found some old info about where they used to be:
30.579214,-95.67835 1375 > NF215 (stay left at Stubblefield Rd., County Line Rd. > NF208a
30.48391,-95.270132 3081 > 1725 > FS255 > take first right
30.541836,-95.159443 2025 - 2.1 mi. south of 150 > right @ FS200 > .6 mi > turn right & go another .5 mi.
I was told that these areas were closed a while back because people kept trashing the places and the forest service got tired of having to clean up the mess. At least that's the story as I heard it.
Welcome, BTW. Can't believe your username wasn't taken by now...
