very cool! the wife has always wanted to stay in a yurt for some reason, but the tipi seems way cooler...especially doing it in that area.
devils tower was neat to see. I remember a store right before you get on the entrance road and they had awesome homemade ice cream. we sat behind the store on a park bench and started up at the devil's tower while eating huckleberry ice cream. wish I'd known about the tipis...definitely would have rented one for the night
