Our trip to the Crimea last year was a lot like camping - here are a few things we were so glad that we brought along...

I have a small travel towel that you can get at camping stores. It's the size of a dishtowel, but I was able to use it to dry my entire self after showers. Also, baby wipes may come in handy for occasional cleaning of hands, feet, lady parts, etc. If it's hot and I'm camping, a quick wipe of the hot spots makes me feel like a lady again. Will you have good bathroom stops? Is the campsite well-maintained? Think if you need to carry a roll of TP in a ziploc along with some hand sanitizer. If you have a sink available, invest in two pair of the quick dry panties you can get at outdoors stores. Bring some laundry soap in a baggie (or travel packets from target) and wash your undies out. They really do dry very fast, and it will help you maximize space. Also, you aren't packing out a bunch of pairs of dirty underwear. As already mentioned, a clothesline will come in very handy. I also stuff a few wal-mart bags in after I'm packed. As obnoxious as those bags are, one or two always seem to come in handy on trips.

Have a good trip!
