There used to be (and may still be) a guy named Hardy Prentice who
flat-towed his race-prepped Triumph TR-3 to Sports Car Club of America
races -- even from California to Georgia when the National
Championships were held there, as recently as 1992. (He towed it
behind an E-Type Jaguar; how's that for eccentricity tinged with
masochism?) There was no way that car was street-legal as a
self-propelled vehicle, but as a "trailer" all it needed was a trailer
license, an approved tow-bar and wiring from the Jag's taillights to
the TR's.

I think there is a possibility that he may not have been legal passing
through some particular state or county, and not been pulled over by
luck. A cop might glance at such a setup and assume it is an emergency,
not a cross-country tow, and not really give it a second thought.

In some areas, you more than occasionally see some pretty amazing things
on the road: cars pulling other cars, wooden bumpers, hand signals for
stopping and turning, pieces of paper with the handwritten words "tag
applied for" instead of a license plate... an E-Type pulling a TR-3
wouldn't raise too many cop eyebrows where I live... it would raise my
eyebrows though, 10 cylinders, 8 wheels, and 5 SU carburettors

Anything pulling an airplane is rare, which makes it sure to get attention.

Did the original poster contact the Maine DOT?

Last thought, if it was a one-time, one mile, Sunday morning, quiet road
tow, I'm not recommending anything
