I agree the drop should be small and inconspicuous, probably water only.
the small weight of the food you would stash for 5-6 more hours of running is not worth the chance it won't be there. I never stash clothes, no where no how (well unless its an official race).
Regarding whether to have the drop at Ryan Campground or at the Keys Rd crossing, does the trail go right by the edge of the campground ? I think the drop location depends on what we feel is most convenient, both in doing the drop, getting the stuff mid run, and cleaning up our mess afterwards.
Also regarding setting up the drop on Friday or on the drive Saturday morning, we need to make sure everyone knows exactly where the drop is, in case we don't all run together.
John and I will get to the campground between 3:30-5:00 on Friday.
