That's why I don't use a hennesey jim - I use a speer type - they're easy to make, because
you can sit inside them easily if you open the bug net - and change. I find the bottom entrance
of the hennesey interesting and cute, but not overly practical.

A hammock that you are comfortable in would fit your bill for camping in odd non-level places,
although bear in mind you need enough ground to get in and out of it - you can't hang one 10 feet in the air and expect to deal with it.

The other thing to remember is on lakeshores, etc. wind will be a factor to your bottom as well
as your top - you may need some kind of windblock if it's cool and windy.
