For example, this old International Harvester bus transported passengers across the Four Mile Portage between Fall Lake and Hoist Bay on Basswood Lake. The passengers would be either starting a canoe trip or going to one of the Basswood resorts.
This bus now sits in the woods near Bear Island River Road outside of Ely, rusting and entombed in a grove of saplings. The below photo shows the driver's side by the back fender. Although it is painted over, you can make out the service being marketed: Canoe Trips.
Today, paddlers can still obtain motorboat tows on Basswood Lake, but motorized land transport is no longer allowed over the Four Mile Portage. Instead of a road for buses, the Four Mile Portage today is overgrown (yet walkable) and partially flooded.
