Well after the brief scare Gary gave me ("I'm too sick to go on the zip line, waaaaa"), we packed up and went on the zip line excursion in Jamaica. I'll let the photos do the talking.
These are the harnesses they strap you into:
They make you feel kick-ass invincible.
Gary skeptically evaluates his pulley:
After you walk down more steps than were in both WTC towers combined:
They take your harness and latch your pulleys on to two sturdy cables, then you just hurtle down them.
Hey, look at me, I look kind of dwarf-like in this picture:
Then after sliding/jumping down a series of 7 cables, you walk down another infinite series of steps and drink a beer while standing in a bamboo tree.
Gary had a beer too.
You know what's pretty?
It was a nice excursion. I felt like I could slide down zip lines for a living when I was done.
