I was wondering if it was possible to do part of the Gorge or if it was even worth it to do part - my husband needs to have his kneed scoped when we return so I'm not sure how he will fair. I also have feet that hurt all the time. So I was concerned w/ walking 6-7 hours. But really don't want to miss seeing the Gorge. Wondered if there was a smaller portion that we could do that would be worth it or if it is all or nothing.
