We went thru Montana to get into YellowStone...then once in...I think we crossed the border and were mostly in Wyoming...Anyway...next on the agenda was to find a camp ground and meet up with Kavan's cousin Doug who we kept playing phone tag with, and we were a little later than we expected too...since the park is so long to drive thru...at low speeds...I think you have to drive no faster than 30 miles an hour...
