I was so used to being outdoors working during my years at SDC, heat and cold did not bother me too much. It was a luxury to be at the diving bell because there were heavy duty blowers that kept air circulating in the tunnels leading to the capsules, and the capsules were air conditioned...but by the middle of the day the heat beating down on the metal roof/asphalt roof of the building and the crowds of 75 people jammed into capsules meant the AC ran hard all day and could not always keep up. I was outside though, at the AP, Tom Sawyer's Landing, Float Trip, Treehouse, Animal Petting Farm, One Mule Swing, and other attractions. Flooded Mine was air conditioned, but suffered like the diving bell when the lines got long and people jammed the loading area and hallway leading to it. Grandfathers Mansion also has AC, but same thing as FM and RDDB. I was young and could handle it then, but now, Forget it. Grandpa likes his AC!
