yeah, done the same. kind of un-nerving but spectacular.
also done the cable to the top of Matterhorn. that one lands at a big hole cut thru a rock pinnacle. that one is really scary.
Ahh, yes, the Klein Matterhorn tram. I have seen it on many occasions but could not bring myself to ride it. The drop as it travels across the valley below is staggering (like 3000 feet!). Of course, anything over 100 ft is going to kill you but mentally, I just couldn't do it.
