More Yellowstone Pictures

We are checking out the Boiling mud.  

 

More Pictures from Yellowstone.  The kids were having fun but it was a LOT of walking.  Don't worry about their crazy expressions.  We have "crazy pictures"  otherwise the kids would be really sick of me taking pictures of them.  It's a lot easier when I let them be crazy, I get a lot more smiles that way.   

The park is huge.  We would love to come back again.  There is no way we will be able to see everything here, but the trip has been a good crash course in America.
