Our local Costco built a new big room for dairy and eggs. It has fans that blow across the opening, and there is probably a 30° ( or more) difference in temperature across the opening.
Hazel loved it.
She’d stand outside, then run into the cold. She’d do a little dance, while squealing, laughing and saying "it’s sooooo cold", and then running out of the room.
She did this over and over, I had to distract her to leave.
