Sectioning from Humpback (855.2) to Gravel Springs Gap (956.2) towards the end of October. Planning on 6.5 days humping. How is the parking at Gravel Springs for six days? What I'd really like to know is it possible to send a "mail-drop" to Lewis Mountain Campground Store??? That is approximately our halfway point. If not.... any other suggestions for a mail drop? I'm not into hitching into towns or PO's and prefer to stay near the Trail.
