In reply to willworkforfoodjnr:
I know you say that you don't really want to be in camp 4 but its not all that bad,we stayed there for two weeks and you can go to a near by campsite for showers at 5 dollars a pop,baring in mind camp 4 is only about 5 dollars a night its worth considering for ease of access.
I was initially worried about how noisy etc camp 4 would be but it was only the bear boxes that were an issue banging when they are shut but they will be at nearly every site.
We did the prow on Washington column which was a great route,about A2/+ as a lot of fixed gear had blown.hope you have a great trip.
