I thought this was The Great Outdoors Challenge ?.
A "self supported" back packing event from West Coast
to East Coast. What with accommodation lists, Sat Navs. Spot
devices . You will not get the Challenge feel surrounded
by all the clutter of civilization or other challengers,
it will just be a long distance walk from "watering hole"
to the next "watering hole". Has as already been said it's
one of the few times in the year you can be free of all
the clutter. Cheers. (Yes, I too am a traditionalist.)
