When the IMAX Amazing Caves movie came out years ago several of the Bexar Grotto cavers met with the local IMAX theater and volunteered to do some rappelling or Tyrolean traverse stunts on the nearby buildings. Several options were discussed but ultimately the rope work was scratched. They did however invite all local cavers to watch the movie for free before it was officially released. They asked several of us to dress up in our gear for several showings. It was fun and I got to see the movie several times for free.
