Ok, just giving this a try. On the way back between Brownsville and Corpus I crossed this creek and decided to pull over. The sand was packed hard and no trouble riding or even to park upright. After the photo I jumped a few dunes...lugauge and all. This might also be a good place to camp.
If the pic doesnt work it's not my fault....IT'S THIS DAMN COMPUTER!!!
