Monte,
Way more challenging than spinning up the Yenta river but still, in the right conditions, realistic challenge.
Flakey, I have 3 mountain bikes and love to ride. Right now don't own a sled, does that make me a greenie?
Technically, I think it does make you a greenie Lynn....
Monte, don't let any of these guys negativity get in the way. go for it, sounds like a good challenge if you can catch the right snow conditions.
I know I've been up riding and it would be plenty hard pack enough off the trail to let you ride a bike easily. Like someone said earlier, I would think that Feb time frame would be that kind of time frame.
And for any help we provide that makes this a successfull trip will obligate you to post some pictures of the adventure....
