Texas Cavers' Reunion, San Antonio, TX

We had a crowd of cavers exploring CaveSim and competing for most-careful-caver for two days at TCR 2015. Photo by Dave Jackson.

TCR is an event not to miss! If you didn’t make it this year, come on down to the San Antonio area next year for this great multi-day event.

CaveSim designs, builds, and uses interactive caves to teach kids about conservation and science. We believe that kids who know better become adults who do better.
