In Minneapolis they have the enclosed walkways going from store to store downtown. It’s been years since I’ve been back - but I recall walking for blocks through all the buildings inside at Christmastime. Never figured out how he could find the car again in some enclosed and warm garage.
Drove home and parked in the heated garage connected to the house - never had to step outside into the cold or snow!
Heh - I guess they’ve been busy since I left!:
“The largest continuous network of skyways – the Minneapolis Skyway System – spans 8 miles (13 km) connecting 69 blocks in downtown Minneapolis.”
