Thank you to Challenger Learning Center Colorado Springs for inviting us to participate in this event for children of Air Force service members. CaveSim was so popular that people waited an hour to go through, and some waited another hour to go through again. Visitors waiting in line learned all about caves, watched carbide demos, and saw our new rope work demo from 10AM-2PM. About 1700 people attended the event.
