"I'm from Massachusetts and I rock climb all the time. I have my own pack, harness, everything. I haven't been to the wall in the Rock yet, though. But a few years along the way, I picked this up. It's a nice way to practice getting your balance."
           "So what is it?"
"It's called a Slackline. The tighter it is, the easier it is to walk on. People can do jumps and flips."
           "Can you do tricks?"
"I can turn around. It's not as easy as it looks."
           "Do people walking by ask to try it?"
"Oh, all the time."
           "And are they good?"
"Not usually."
