The old PCT guide book was the size of your average " TV GUIDE'. No computer list , GPS or other goodies to help here. We were happy to have what info was there. Even Early folks like Eric Ryback, Dave Odell, Toby Heaton or Wayne Martin had nothing but a few early maps the forest service printed out amd then there were three choices between the permenent route, temp route or alternative route. PCT 1977 was as hard or maybe even harder than today's CDT route finding problems.......
