So... I like every other boater on this forum have been folowing this post.(not as good as the LIL Man in the canoe from lasy year but entertaining.
You said you want this to be a FULLY nude trip correct? How ever I looked at your web site full of leathered old folks and in many of the pics men and wommen had cover ups of some sort. Paint sarong, shorts, towell, etc.
Personaly I could care less what a bunch of life lovin nudist do. However one must show proper eddicut(sp) where ever they are! Take your trip but take some clothes as well. When there is no one to see Well Hell GET R DONE! But if a group comes up or you come up on one

Than throw your light body cover on for a few munites and when they leave disrobe. Cant it be that easy. When you are at camp at night run arround like wild people and do what you do! Some of us have famlies and young kids we want to bring on the river. I sure as hell dont want my daughter asking why is the overweight lady is naked on a raft and what is that hanging from her body.
Hope it works out for you. If it does we should have a burrning man fest on the river. We could call it Burnt to a crisp man cuz Im naked all day fest! Remember somme people ay Burnning Man do wear clothes.
