Here's something you may not have thought of for your Alaska trip. If you have a submersible pump that is not too heavy & bulky you will be able to put it to good use. The attached picture will show you why. I only had a bucket and spent an awful lot of time doing this. With a pump you can stop by a river anywhere and rinse off.

So this is what we have to look forward to. Nah! Submersible pump - never thought of something like that.

Am I just seeing things or are you really, really close to a tree on the right? Fred
