Bob & Corey,
Enjoy Yellowstone! I drove through there with the family this summer on my way from Ft Sill (Oklahoma) to Ft Lewis this summer. WAAAAAAy too many idiots driving around. (slammin' on the brakes and stopping in the middle of the road to look at a coyote??!!) I was told that it was much more enjoyable in the fall and winter. Sounds like snowmobiles may be off limits there in the not too distant future due to the tree huggers (too much noise). Enjoy your vacation, and take care of the back! I'm sure that the hot tub will be a cure for many ailments We'll try to leave a fish or two in the river for y'all, and we'll keep our boats right side up
