After a couple weeks back in North Dakota it seems like its been a lot longer than that when we where in Yellowstone.  My favorite part of the trip was seeing all of the animals so close, the bighorn sheep was the coolest I thought.  I also enjoyed the scenery we saw on the hikes, especially the lake hike when we were on the shore area.  I thought it was cool to see all of the hydro thermal effects and how different they were from each other.  Finally just learning about all of the wolves and their stories was fun too.
