Thanks for the info. I was at MacDougal's Gap last Sunday morning for the sunrise (the link in my previous post). I went up the Greys to where the road is closed - sure do miss being able to make the entire loop-drive.
I may give the Box Canyon hike a try - need to do a bit of conditioning though, it has been quite a long time since I did much hiking (and my knees talk to me a lot these days - some days they scream!)
If you are in the area, let me know.
