Homer is a trusting soul isn't he? Why do you use those kind of ties, rather than crossties?
I don't really have a good place to put cross ties, and I wanted them to be good and used to high-lining for camping... Now that I've used them, I like them a lot better than tying to a tree or to a post, because the lines are totally out of the way. And I've found it's a really safe way to tie... they really can't hurt themselves. If they do startle, they can run in circles, but they never sit back on the line.
