I've heard theres a great KLR friendly route from Ogden Valley to Island Park.
Has anyone done the ride? GPS coords?

I have done from south pass, wyoming to dubois and its a windy ride going thru the pinedale stretch, but absolutely awesome once you get into the mountains.

I'm hoping to get as far as Yellowstone on my trip next month. I'll be coming in from the south/south-west. Any idea if I can expect to get through and into the park that early in the season? I'll probably be at Yellowstone around mid-May.
