Here's a super-panorama of the valley.
You start out going south on Reddington Road. According to Google maps, after a while its name alternates between Reddington Road and N San Pedro River Road. Also, sometimes it's spelled Redington and sometimes Reddington. When it gets to Tucson, the name changes to E Tanque Verde Road. It's a dirt road, but it had been graded recently and most of it was in very good shape (though I still wouldn't drive a minivan on it, and there were a few rough spots).
The road got up around 4000 feet. There was a storm trying to follow me, and with the altitude and the storm's shade, it got down into the 80's. Very nice. I got sprinkled on a few times, usually when I stopped and got out to get some pictures.
It was a pleasant, relaxing drive. I want to explore more around the San Pedro River some day. Click below to see all of the pictures.
