I used to know a gal a long time ago who tried to walk from the Mexican border to the Canadian line along the Sierra and Cascades. She had to abandon her attempt about 80 miles shy of British Columbia. Her knee gave out; she just couldn't go on. No shame. I'm an old Sierra backpacker myself. I know what twenty or thirty miles of rugged trails under a heavy load does to a body. 1250 miles! Good lord, man! I tip my hat to you.
