A couple years ago, I went with a friend to Wildcat Mountain in New Hampshire, which offers visitors the unusual opportunity to leap from a mountaintop, suspended from a zip line, soar through thin air (and in my case, a stiff breeze) down the mountain, and then bounce off a tension spring at the bottom.  Staff at the time said everyone reaching the bottom laughs aloud upon hitting that spring, and we were no exception.

I notice, however, that the residents of Los Pinos, Columbia aren’t laughing when they invoke a similar zip line suspended 1,200 feet over a river as part of their daily commute.
