Midchuck I am concerned that the sun shower information and your musing about buying a digital camera are contained in the same post...just don't try developing those pics at Wal-Mart.
Kendall, a sun shower is a plastic bag with tubing and a shower head attached, You leave it in the sun and it warms the water beautifully. Then you hang it from a tree or whatever and can shower with it!
We set up a shower at our campsite at Brushwood with a garden hose hooked to the water supply and rigged it up over a wooden pallet; you just use the hose spigot control after turing in the water supply. more complicated than a sun shower but we return every year, so...also since the hose lays in the sun it also gets nice and warm...but you have to hurry before it gets cold!
