There's nothing more to be done now, except walk.
I am well rested, my feet are looking OK (except for some dead blisters), and my box is packed with all the stuff I'll need for the ordeal. The weather looks as though it's going to be nice too, which is a bonus.
I feel strangely calm -- or am I numb? Apprehension gilded with excitement.
More after the event . . .
