Pond Boss Forums INTRO Questions & Observations Zip Line

I always wanted to install a zip line into my pond. My house is close enough and high enough that I've dreamed of putting a line from my deck down across the pond. What a kick that would be at summer deck parties! The line would run about 300 feet to the opposite side. I did some searching and you can buy the trolley device needed to do this. My only hesitation is that the line would run for about 100 feet over dry ground where a person would be 15 feet high. Don't let go early or ouch! I'd do this in a flash if I thought no one would get hurt.
