Casey’s Barn 1961 – the office and lab were on the 2nd floor, probably the left and middle sections. When you entered the barn you went up a flight of stairs that gave onto the cramped office area. A door separated the office from the lab area. It smelt very strongly of rodents and took some getting used to when you first entered. The lab area was divided into three sections: front sections was where the weighing and other tests were done; the middle section had the six habitats in individual rooms; the back section had a huge maze.
