See my other comments. Good starts to these pages, but same problems apply. I will up my vote.
Agree with your statement that if you're going to take the time to make the drive, you should spend at least a few days in the area. That drive to the trailhead is epic.
Epic is a good word to describe it. Our Sedan made it in and out, but it sure was nerve-racking. I guess it only added to the fond memories I have of that trip. We did a big loop hike and part of it was along the Middle Fork. Some kind rafters spotted us on the trail one morning and pulled over to the bank and offered us some beer, "High-Life" at that.
