I attached 2 American Flags onto the rack on the top of the trunk. The masts of the flags fold forward to put the bike cover on. The problem is that apparently because of the large windshield and my body, we create a vacuum and the flags fly backwards! This causes the masts to fold down onto the trumk. I'll try tightening the hinge bolts a little more, but has anyone else here ever experienced this problem? A real Bummer! Owen.
