I've had a Hennesey for a few years. A few comments:

(1) I've changed clothes standing up. If the hammock is low enough, you can put your feet outside with only thigh and below outside the hammock. I've also changed clothes completely in the hammock...more awkward, but doable.

(2) I store gear in a mesh duffle bag hanging with a separate rope between the two trees. The mesh duffle is positioned immediately below the entrance and off the ground. If I want something in the middle of the night from the duffle, I move my legs out, straddling the duffle, and put my feet on the ground (onto my sandles, which I keep outside on the ground). If I want to get completely out of the hammock, I put both legs to one side of the duffle and get out.

(3) In camping in state parks in Indiana and Michigan, I've never been denied...and I ask in advance. And I'm also convinced that with the webbing, it would take a heck of a lot of hammock camping before any damage occurs, if ever. That's even if a lot of people were to hammock camp, and there aren't very many.

In summary, the Hennesey is quite an innovation...a definite advantage over a tent. By the way, I've never failed to find two trees the right distance apart, either...although I'm sure it will happen sometime. I'll either use as a bivy or just use the fly as a tarp.
