The zipp lines were great but cameras need to be placed on the platforms to make sure the guides are not mistreating people. I am an older woman and was last in line so there was one of the guides that apparently chose to dislike me. Only me and him on the platform, no witnesses. At one platform he grabbed my harness and jerked it 3 times,and said nothing. I'm assuming it needed to be adjusted but he should have said something first,,,I almost fell. At the last zipp he was at end of Zipp,,he did not catch me and I hit the ground hard. My daughter was standing there watching and as we walked off she said geez,what was that,,he didn't do that way to anyone else. The other guide Joe was a great kind hearted guide.
