Toms Turnabout

Toms Turnabout .. no apostrophe.   Is this the story of a boat belonging to Tom, or an area to turn your vehicle around in front of Tom's place on a small jut of a street off of Hammand Bay Road?  (there is a largish area for a turnabout which is not at the end of the the street).  Not sure of any of these, and again, I'll toss this out to you who may be 'in the know' to provide some clarification.

Totally beside the point, but this is what our cedar hedging will look like when it matures.
