In response to mountain goat's reply:
We backpacked from NRim to SRim in Oct03. We spent 2 nights at Phantom Ranch in the campground. The campground was about 1/4 mile away from the Ranch. The hike between the campground and the Ranch worked wonders to loosen up the muscles that had pretty much locked up from brining us down from the NRim. By the second morning we were ready to climb out. The climb out wasn't easy, but, it turned out to be less punishment on the body than the pounding you take hiking in.
The Ranch food was the greatest, make sure that you reserve your meals well in advance. We had breakfast as well, if you are hiking out, make sure to get the early 5am bfast. You want every bit of hiking time before the sun starts hitting you. We didn't purchase the lunch meals, the bfast and the evening meal were more than enough.
The Ranch is a good spot to reload on fruits and gookenaid for the hike out, less to pack in.
And don't forget the Ranch is the only place to get Ranch T-shirts. Nice place to get a souvenir t-shirt, and you didn't have to hike it in, and it's clean and doesn't smell.
