We had our last outing today. We went to Fermi Lab - a very famous research place. 

This the sign that greeted us at Fermilab. Made me laugh so i have to show it.

I’m not sure how a proton runs but i’m sure it’s funny. 

The next thing we saw was a bubble chamber window.

It was a rainy day so good to be inside. 

We got to do some paws-on work in the lab.  Well, hands-on work for Heinie.

Later outside we stopped to see the buffalo.
