Yessir, I am a single Dad with Custody. I did have a friend fall on opening day of gun about 15 years ago, the last step into the tree was a dead branch and he broke his back, had no cell service and had to crawl to his truck. I know these kind of things happen but are an exception to the rule and not the rule. Out of everyone I have ever hunted with, or known to hunt he is the only one that fell out of a tree. I hear of 5'ish of these kind of stories every deer season here in NY, maybe more I don't hear about, but there are tens of thousands of hunters so the odds are small and akin to wearing (or not wearing) a helmet when riding a motorcycle. My early years of hunting I didn't have a treestand or pegs, I scaled the tree and stood on icy branches, THAT was dangerous lol
Like I always say, to each is their own and maybe at some point my old age will have me less comfortable on a platform and convince me otherwise but as of now I don't see me jumping into a harness.
