Hey Shane, I made it to West Yellowstone today, heading on westward tomorrow.
To stevensville, MT. If you are planning a eastward trip thru Yellowstone, I'd recommend the Beartooth pass thru Cooke City, MT to Red Lodge MT. It is one of the best motorcycle rides I've come across nationwide.
I'd also recommend taking hwy 14alt from Lovell, WY ( NE of Cody, WY) thru the pass to Sheridan, WY. I did both of these rides today and they were spectacular. Got caught up in a pretty Nasty storm at the top of the Beartooth today, but it didn't last long. Some rain, some sleet, some hail,some wind..... WOW, what a ride. (I'll post pics when I make it home to WA) The weather should be better tomorrow. I would defiantly give it a look, even if its a bit out of your way.
Ride safe, try not to run over a Buffalo in Yellowstone....I think I saw close to 1000 of the buggers today. they are everywere. Not to mention 2 grizzlies and a black bear
