The only time that I've walked into a hitch was on my own truck. Up here if you leave it in for a couple of years you won't need to worry about it coming out. I've hooked the hitch of a 4 YO pickup to a tree and still not been able to remove it. OTOH I have 2 which I've picked up out of the road over the last few years. Both the same drop though, I wish that people would be more considerate when they lose things and realize sometimes I could use a longer drop.
