I’m planning an August Brooks Range trip, and am thinking I’ll want to cache boats for a couple of days of side-trip hiking. I found this old thread inquiring about hard-sided cases for a cache, http://packrafting.org/forums/viewtopic.php?f=2&t=1017, but I haven’t seen anything since then. How have other folks approached this? Has anyone had problems with just leaving a boat, pfd, and paddle under a bush in a nylon duffel? Or is normal practice to cache boats in a hard-sided case or bear can?
