Rain and cold in the morning then the sun came out. Went to Home Depot and picked up some chain which I cut into 45 and 35 inch lengths. Moved the ceiling hooks over 18 inches and installed the chains. The hooks needed moving to allow 12 inches of horizontal vent pipe per the instruction manual. I rebuilt the lower light shelf in Libbie's office. There are now 2 shelves done. The upper shelf has plants on it so it will be more difficult. Dinner was Krogers fried chicken with macaroni and potato salads. Listened to Nabucco live and also packed up a box of 10 pots for a customer.
