Yellowstone with Gma and Gpa

Last summer we tried to go to Yellowstone but it was too early in the year and when we went up to Idaho for the trip it was snowing in Yellowstone. This time we planned to go in July because we figured we had a better chance of warm weather.  The unfortunate thing about going in July was that there were a bunch of tour busses full of tourists, and there were tons of people everywhere.  That seems to be the trend with just about all the national parks.  Which is unfortunate.  We were pretty lucky to be able to go on this trip with Gma and Gpa.  They are experienced with the park, and Grandpa is starting to slow down.  In a couple years he might not have the stamina for a trip like this.  Even the longer walks were a bit too much for him, so he spent some of the time resting in the car.
