Yellowstone Park

We left Thermopolis, WY this morning and drove to Yellowstone National Park.  We had the camper attached to the truck, so we couldn't stop and sightsee.  We did see a lot of thermals from the road and a few animals, such as bison and elk.  The last few days in South Dakota and Wyoming the temperatures reached 100 degrees. As we were driving through Yellowstone the temperature was 53 degrees.  It is supposed to get down into the 40's tonight.  We are currently camping in West Yellowstone.  It is actually in Montana and is right outside the boundary of the national Park. Tomorrow we plan on spending the entire day sightseeing.
