Replying to Slack Lines

Anybody ever play with them? I just got introduced for the first time today at Kits Beach. I got the hang of it pretty good and was walking around with composure (and even a few tricks) by the end of the session. I'm actually going to have to make one now, they're way chill.

Those of you not yet introduced, it's when you strech a ribbon of nylon rope between two points and balance on it tightwire style. I tried it on 1 inch nylon rope and it was awesome.

My mind is racing with possibilities.
