Safety systems lacking - Let me start by saying the people working were all extremely friendly. This is a small operation, not like the big operators the push 100+ people/ day through their facility. We were the only ones there. As far as I could tell we were the only clients for the day. The setup was nice and it was obvious a lot of time and effort was spent in creating the course. My concern, and resulting experience is with their safety systems. I noticed as we were doing the regular zip lines their carabineers did not all lock. The one holding my harness together with the straps in the front did not, nor did the one they attach to the pulley. We completed that portion and moved on to the Superman line. They changed our carabineers for some that did lock, which made me feel better. My wife and 2 kids went first and everything seemed to be fine. When I went, it didn't go so well. There were 2 newer guides and I think they just got in a hurry and weren't paying enough attention to safety procedures. I'm still not positive what happened but when I got to the end of the line and hit the safety stop line everything went wrong. My best guess is they didn't have the rope pulled tight and there was slack in the rope hanging down by the cable. The rope bound and I came to a sudden, complete stop. The rope slid across the side of my neck giving me a severe rope burn. I don't believe there was anything intentional, the guides were just anxious to be done working for the day. When we got back to the main facility they were quick to be off once our gear was removed. They did apply some antibiotic ointment to my neck before leaving but that was the extent of the interaction after my injury. Again, overall I think the people were very nice. They just weren't up to par on they're safety protocols and the equipment was not in the best condition. I'm positive my experience was a one off. You just can't afford a one off with this type of activity. I feel very fortunate the rope just caught the side of my neck. Anywhere else and the result could have been much different.
