I remember something in the paper about a couple of guys who had never
done any climbing. The rode their mountain bikes into the desert,
abandoned them, walked a ways and got the bright idea that it would be
fun to climb down a cliff. Halfway down, the dropped down onto a
ledge, which left them with no way back. I can only imagine their
horror when they found no way down.
