All this talk about zip lines is funny to me! They look like a lot of fun, and if I was younger and thinner, I'd try one out. When Tom Sawyer's Landing was built in 1980, sometimes the guys from the diving bell would go on up there to assist the other attendants. There was a cable slide...(what I would call a very low to the ground, kid friendly zip line)...and it was removed after a couple of seasons because some kid did not listen to instructions given to him by an attendant, and went crashing down to the board wall at the opposite end. Rumor I heard was someone threatened to sue, so, guess what? Goodbye cable slide! Same thing with a fireman's pole that was in the Tom Sawyer's landing playground area. It left after part of only one season, if I remember correctly. Now, all these years later, we've got cable slides (zip lines) way up high in the air for adults and kids? Are people signing disclaimers prior to riding, saying they won't sue if they screw up and get themselves hurt? Oh well, life goes on...
