If you come in from the East I would bet you could get a tow pretty easily. Almost all of the skiers around here use sleds for access. This is the hairpin on a weekday late last season: http://d.pr/i/6SjH
Our camp chairs were stolen from one of the upper sites at COR this past fall. I stopped by the ranger station on our way out just to mention it to the ranger (didn't want to bother with a police report or anything). He was extremely nice and seemed genuinely disappointed, saying that theft is extremely rare in COR.
Quick update: I went up to the North Fork crag yesterday. The road is fine. There is a newish clearcut where the "trail" starts. The crag is extremly overgrown, highly chosstastic and the fixed draws look extremely weather worn.
Yes, sorry, I should have been more specific. I mean the North Fork crag out in North Bend. I was out there in 2002, but heard that the road might have washed out recently.
