While out camping last weekend, Snyder and his friend thought it would be a good idea to string some wire between a pair of trees and use a jury-rigged pulley to travel from one side to the other.
It was not a good idea.
"We'd been on it. The kids had been on it," Snyder told news station. "I just took one more step up and jumped, and when I jumped everything stretched out and once I hit that stretching point, the weakest point was the handle so it gave out."
The video shows the 44-year-old falling some 12-feet and smacking the ground with his back — hard.
Despite the alarming sounds of agony emanating from Snyder — "it sounded like I was dying, and I felt like that" — he actually emerged from the incident mostly unscathed, save for some bruising.
It certainly could have been much worse: Snyder had undergone neck surgery three years ago, and was in no condition to be falling from homemade zip-lines.
At least he's learned his lesson.
