There was nothing along NW 67 Avenue north of the Palmetto at this time. NW 67th eventually ran into the Country Club of Miami just above what is now NW 186th Street and traffic skirted the east side of that development on Bob-o-Link Drive until the county line at NW 199th Street. There used to be a private airstrip on the east side of Bob-o-Link Drive with several private aircraft parked there and owned by residents of the Country Club of Miami.
There also used to be signs on poles for traffic exiting the Palmetto at NW 67th Avenue stating "New Town Miami Lakes" with an arrow pointing to the south where Miami Lakes was. However, over the years people started moving into developments north of the Palmetto and rather than use "Carol City" which was closer they told people they lived in Miami Lakes. I surmise they removed the "New Town Miami Lakes" signs because they were confusing people going north of the Palmetto.
