@Likeapuma: interesting that you mention folks with bad backs yet being interested in hammocks. That's a good thing! The response I've gotten from several of the other program staff has been, "Not interested. I have a bad back and could never sleep in a hammock.". The subsequent discussions have not been fruitful. ;D
So far, I've given away three hammocks to program staff. One guy now brings his along to lounge and is sort of working towards hammock camping. Another guy gave his to his daughter because of his bad back. Didn't even try it. The third guy hasn't even opened the hammock yet, and the hammock was given last summer.
What is that saying about horses and water?
Oh well! More tree choices for me!
