I happen to have been up there this weekend, salmon fishing right by ruby creek, when we stumbeld across two nice fellows, one riding a 300 exc and the other on a yamaha 450 four stroker. a few minutes down the road, we ran into another bunch coming off a snowmobile trail.
Im betting I know who that 450 and 300 were. Was that a WR450, with aluminum frame? If so I was riding with them in the morning. They were just out dual sporting thats all. No event that I know of.
We started at White Cloud. I rode with them for around 15 miles of trail and had to bail (busy saturday lots to do). They continued north dual sporting to/till whenever.
I was on a 300XC-w. I never made it up that far though. I dont think either of them are on this board.
