We went to watch the Eclipse in October, it was great weather, no clouds.  We had a great time.  Our RV site was roomy and there were a few sites surrounding us that were not occupied, which allowed us to spread out, kicking soccer balls and throwing footballs.  The kids loved it.  The boat launch is nice, we didn't have any watercrafts but will maybe try to bring a kayak or canoe next time we visit.  

The location is not far from The Woodlands and Houston, and other attractions.  But still in a quiet area.
