I've ran Pritchett many times over the years and have never gone thru Hunter canyon! I didn't realize it was an option and I'd be willing to bet that most people that run Pritchett have done the same thing.
I've run Hunter a few times when getting off Pritchett late at night.... not exactly ideal when you're just wanting to move on out and get back to town. I do like the canyon. I don't know if I've been in it since I had an XJ?
