Obsession

I can't stop thinking about the Grand Canyon. I'm planning a trip to take my mom to Phantom Ranch and back out, but I want to go back. Now. Since our trip is likely a year away, I'm thinking of a mid-fall weekend jaunt from Rim 2 Rim 2 Rim. Since the North Rim will be closed, I'll either need to do the whole thing at once, or stay at PR overnight. I am dying to go. It consumes me. Why is this?
