I need help planning a 4 day/ 3 night trip in the shenandoah in early september. It's gonna be my wifes first trip, so looking to take it tairly easy. I heard that there are a lot of resupply point on the trail where you can get real food. That should help take some of the roughing it part of backpacking away for a first timer. What is a nice scenic section of the AT in the park to do a 4 day section? How often does one come across water sources in the park?
