First rim hike came earlier than usual this year. I've done this loop a few times. Its a good solid day. I didn't run into too many hikers. Met up with Karl, Kathy, and Chumley at THAT before I drove back to Phoenix.
The Pine TH is great-- its seems like they're constantly rerouting everything back there. Its like a new hike every time. Even the Donohue has gotten some maintenance love.
