Grandpa Christensen called a few days ago asking if he could stay at our house while his SUV had some work done in Salt Lake and we told him we would love to have him stay with us. We picked him up at the repair shop, went home and changed Luca and then started having fun. Nick & Grandpa wanted to visit Hill AFB's Aerospace museum so we loaded up the car and headed out. It was a little cold and there was still some snow on the ground but the "boys" had so much fun looking and talking about the airplanes. Nick, Grandpa and Luca all seemed to have a good time. Grandpa only stayed for one night but I think that he had a good time.
