Day o' fun with the Sandbergs

We met up with Richard and Deanne and their three kids, Caradyn, Savannah, and Nathan last Saturday. We had lunch then headed up to the CU campus in Boulder to see where Richard works and goes to school. He is finishing up his doctorate in physics. They have this amazing laser up there that he spends a lot of time with. I didn't understand a lot of what he said because he's brilliant, but it was lots of fun. Brian was so excited to play with the laser!

This is Matthew on the way to meet the Sandbergs. Doesn't he look excited?!
