I respect the self support thing. After Reading WE SWAM THE GRAND CANYON I admire anyone who would forsake the creature comforts for the satisfaction of doing it the hard way. So pardon my insolence but have you considered renting an 18 foot raft from PRO an bring on a qualified boat person to haul gear? Think of the decadence of lots of BEER, Freezers with food that is much better than dehydrated, Tents and other obscenely decadent, heavy and bulky gear. Did I mention the GROOVERS. Just a thought.
I'm planning a trip to The Trench myself and I'm sure I want some kayakers along for safety. It will be my honor to carry their gear and beer.
If you stick to your plans I will certainly admire you spirit. Send us a trip report and I heft a cold beer to you spirit. Best of LUCK!
