Tanks Rapid, LOL!
I fit a lot into a 3' wide space. No need for full bloated O structures when you can achieve a better result with flats and backs. Since a commuter sees the back of structures on the ROW, I model everything backwards. Keep it simple, no need for the cluttered look.
O sales are not as brisk as years ago, maybe MTH will step it up a notch and do something....... BIG LEAGUE.
