Shower will be $4, you can use a new clean towel for $1 or buy the towel for $2. I have no pictues of the showers. They will be inside a 10x10 EZ UP tent, with a divider with 2 sides providing 98% privacy from one shower to the other, 100% privacy from outside. Total of 2 showers. If the guy in the next shower wants to peek at you, he will be able to with a little effort! (I was thinking about letting women shower free). Thick rubber mats to stand on, a chair and hangers for your clothing. Showers heat with propane, and they get hot. You should not have to worry about cold shower. Each shower has it own separate heating element.
The years I have been there rain has not been a problem, couple of years with a ton of dust and a couple of days of super strong winds.
