Suspicious people sometimes wander on to college campuses. I suppose that explains why the security guard approached me as I was painting in a section of the main quadrangle and wanted to know who I was and if I had permission to be on campus. My former classmate and I had entered the front door of Main Building and asked someone in the first office if we could set up and paint on campus. We were welcomed. Wrong authority. We had to proceed to the proper person to explain our presence, thereby wasting good morning light time. Next time we will know which office to enter. At least this little painting was completed after the interruption.
