Does the tortoise ever go in the pool with you? I know they are built to withstand the heat, but still. The only way I loved 109 degrees was drunk with an ice chest of freezing beer and wearing nothing but a wet bathing suit while on my old ski boat at the river. When you are waterskiing and it's that hot out it feels so good. Warm air breezing by as all the cool water splashes you just right.
