lol Bruiser, that's Martin, I'm Matt (one of them) 
It's really not as bad as you think Martin...
Bruiser I'm not 100% sure but the big campsite Martin mentioned is on the Argentine Pass trail. Once you turn off the Guanella Pass Road you go up a 1/4 or 1/2 mile and there will be a culvert and a place where the creek crosses the trail. The campsite is very near that location, maybe slightly above the culvert.
