It's bearly possible

The dusty marks shown below are on all four doors, and the tailgate, of our rental pickup. While a less exciting explanation may be the case, it is true that (1) the Y warns that black bears sometimes come on the grounds, (2) the Y further says that some of them try to open car doors to look for food, and (3) our cabin is on the edge of the property, next to a wooded area.
