Cascase Loop (before)

I've got my bike all pack up and ready to go. 3 paniers on the back and a bag on the front. Tomorrow morning Ben and I head out for a 6-day biking and camping adventure over the Cascades and back, hitting Wenatchee and Chelan (I think) ranging from 350-400 miles. I've never done anything like this, but Ben is a veteran, and he says I will be ok, but in case I don't make it back, I want a big funeral and lots of uncontrolable sobbing.
