Quick update:

Despite camping at a camp ground with showers this weekend I convinced the DW that she didn't need them (the fact that it would have cost us 10 bucks to both shower helped...damn pay showers!). We tried to go as low tech as possible and washed in the basin/bag which came with my GSI Dualist kit and about 4 cups of hot soapy water for the both of us...plus a J-Cloth.

I think to make it work better in the future I'd have to take a 'bird bath' (thanks Susan, I like that term) twice a day and she'd definitely need something more for her long hair...if nothing else just to get it good and rinsed out.

It's a start and already I'm proud of her...I didn't think she'd go this far.

Thanks for the advice folks!
