I used the CD-audio tour at New Mexico's Carlsbad Caverns and was impressed that it worked in such a high-humidity environment. It's also infra-red - meaning that it starts at a particular place on the tour. I found, though, that I needed to stop and listen and not continue to walk when someone was speaking. As you can imagine, it's important to watch your step in a dark cave. Antenna produced this tour and provides the equipment. Alison Glazier Media Projects J.
