Live near the border and want to zip across for some R&R, or perhaps to pick up some authentic Canadian maple syrup? When filling out the ThreatSwitch travel wizard, Just refer to yourself as the "Supplier" of the car you're using.
When you create a pre-travel report, you will select "car." Then just list "self" as supplier, and "home" as the pick up address. Be sure to check the box to show that pickup and dropoff locations are the same, as shown below.
