Wow thems some pretty awful stories.

Only once have I been hasssled, driving a car my Mother In-law gave us from Florida back to Toronto.  Shortly after 911.  They insisted I had to pay duty.  The car was made in Canada & bought in Canada.  I had notorized Power of Attorney over the car.  After about an hour of them saying I gotta pay duty and me saying I don't the supervisor came by and looked at my paperwork.  Supervisor muttered to the subordinate, "He's right, we can't touch him."  Subordinate said, "We're going to let you off...this time."  I bit my tongue, smiled, thanked and drove off.  Never felt so happy to be back in my home country.

That was my last 20 hour drive.  From North Carolina to Toronto.
