I really, really wish you wouldn't put any caches on Golden Ears. The last thing that poor mountain needs is a bunch of geocachers running around poking through rock piles etc. Yes I know most geocachers are respectful of the environment but it's the few who aren't that will ruin it. (There is an example on one of Hayward caches where the guy was too lazy to walk the 100 or so meters up the trail so he cut through the blackberries on a rather unstable hillside. And yes, I'm too lazy too grab the url).
As for actually making it up Golden Ears during the Christmas break, I'd be very impressed. I'd be surprised if the road was even open, it seems to be closed 2-3 times a week already.
