Solar Showers

From scoutstuff.com: How about a solar camp shower for $4.88?  Not sure? Amazon.com lists a lot of choices as well. Let us know if you think these are good ideas?  These are also useful for having a supply of warm water to wash hands when you hang it near your camp kitchen.  Downside, heavy when filled (8.3 lbs per gallon of water).  We have one that looks a lot like this one in the picture.

But if all you have is ambient water showers, this can help cut through the cold. For our unboxing and review read on after the jump.
Here is a slide show of the unboxing of the solar shower with comments.

Pros: 

1. Warm water for washing or showering. 

Cons: 

1. Heavy. 20 liters is equal to 5.283441 gallons and one gallon of water weighs 8.34 pounds, so if you fill the solar shower to 20L you will have to lift over 44 pounds to hang the shower.
2. Time to prepare the water.
3. What if there is no direct sun?
4. The risk of someone else using it (with or without your permission)

Bottom line: We are taking it to the Summit Shakedown.  Will report back on it afterward.
