I hauled one about 100 miles home on the trunk of a Mazda protege once. Laid it across the trunk, legs facing towards the car. Rolled down the rear windows and tied a rope between them, then rolled the windows back up most of the way.

Hauled a bunch of deer on a cargo carrier behind a Buick park avenue with a trailer hitch.

Also tied a bunch off on the spare tire on back of a jeep, across the roof, on the front bumper, etc

Bring some rope and you will figure it out.
