"Earth Day"

Today was an "Earth Day" event at the National Guard station in town. One of the gals I know from AZBCR works there and got us invited - thanks April! There were 400-500 kids that came through. We brought 4 miniature horses, Foxy, Holly, Ozzie and Sunshine; and 4 miniature donkeys, Betty Lou & Jeffrey, and the two new girls, Milly and Josey. April was gonna hang with us but ended up stuck in her office; Shirley and Randy and a couple of "Target" volunteers made up my crew. Can you guess what Randy's favorite part was?
