well hello, i am quite new to the backpacking world, however, i have applied to be a crew member on an Appalachian Trail Summer Work Crew at the end of July. This should surely be a great experience. I am unsure of what to pack for this week long outdoor work scenario. They provide shelter, food, and tools. I'm not sure, however, if a hiker packs different outfits for each day or if you only pack maybe 3 sets of clothes and then wash the clothes in a river or stream during the trip?? it seems that seperate outfits for about 7 days would be quite heavy in your pack. And also, if no showers are provided, how do you wash?? in a creek or pond or one of those "packable showers"?? Thank you and any feedback will be much appreciated.
