I am planning to hike the JMT south-to-north starting Aug. 24. I will have someone drop me off at Whitney Portal and am planning to take YARTS and the train back to Southern California. I would like to send a package containing clothes, etc., to somewhere in the Valley. Obviously, the first thing that comes to mind is the Post Office. However, the limited hours could prove a problem. Does anyone know if there is anywhere else in the Valley that will receive and hold a package for a JMT hiker?
