I've zip-lined several times in the past, but it had been a long time ago. The 12-line tour took seven of us about an hour and a half, and my boys thoroughly enjoyed flying through the air - a first for each of them (ages 17, 14, and 9). I felt perfectly safe, and the staff were very friendly and professional. They provided water twice on the trip - a very nice gesture. Both of them were engaging and thorough in their safety inspections, and I could tell they really enjoyed their jobs. Thank you so much.
