JMT is on my list of one of the trails I want to do when I move out west. I enjoyed your pics.
I am curious...if you have to put in for a permit so far in advance what happens if the weather is just awful? You have to put in for another one? We don't need permits here in the East and I have to say that I'm glad for it as many of my hikes are spur of the moment and weather dependent. If it rains hard, I bail. I don't like to get to the top of a mountain and see nothing.
For me, rain is a pain and I only have fun in the sun. Yes, I'm a wimp like that.
