zodi makes a good product, and 100 degrees is pleasantly warm compared to right out of the hose.
i have a ice fishing tent thats 4x4x6 tall would be a perfect shower room for roughing it, also a good port-a-potty room.
we camp in state parks to use their showers and rest rooms. one less chore for me to deal with that way.
i will be boondocking
for a week next month, while i do a sturgeon guarding volunteer thing, but theres a state park a few miles away and they are glad to let the volunteers catch a shower.
P.S. almost every state fishery dept, or natural resources dept, needs volunteers for one thing or another. i work with our dnr's stewardship program every month. its a great way to pay back some of the enjoyment my state's great outdoors has given me over the last 61 years.
plus i get to meet some great folks. lots of collegs age kids volunteer, and they will make you realise we don't have to worry so much about the future, theres still plenty of great youth out there.
