Caching with no cell coverage and no stand alone GPS unit
I'll be taking a solo hiking/MTB trip later this month to a rural region with well documented areas of no cell phone coverage. I'm confident in my skills navigating trails and paths with a compass and paper maps but I'm not sure how to go about caching while out there. Is it a hopeless cause without purchasing a GPS unit? How have others gone about it successfully? From what others have told me, I won't ever be more than 15-20 miles from areas with reception so I'll be able to get a signal when needed, just not WHERE needed.
