Opa-locka Executive

1Aircraft scrapping area

Via the easy anti-clockwise tour of the facilities you start in the northeastern corner with the aircraft scrapping area. The former runways are used for storing aircraft until they are ready to start flying again or to be reduced to aluminium cans. All is done in the open air and there is only a small administrative building. Therefore identification of the aircraft is an easy job from the abandoned aprons west of the building, unless aircraft are parked in front of each other or nose on. However, photo opportunities are limited due to the fences and equipment.

2FBOs

Close to the main FBO the large propliners like DC-6s/DC-7s are parked. They can be photographed through the fence, in particular during the afternoon, when the sun is in the right position. A camera with a small lens diameter is advised, unless you want to get caught by security staff for attempting to climb over the fence using stairs...
Next drive around, take every possible road to get in between hangars to try to identify parked aircraft. At some location you may be able to make a snapshot through the fence, though beware of security staff.

3Coast Guard

The US Coast Guard facilities are southwest of the spot 3 marker. However the gate is already close to where Wright Road turns north to Hoxey Road which prevents you from getting close enough to see any aircraft. These are behind the buildings.
Driving top the north of this area gives you a chance to look at the large western apron (although that is often pretty empty) and view the center ramp from a different angle.

4South side

For reading off Coast Guard aircraft, you need to get off the airport. A suitable location is at the parking area of a business at the corner of NW 135th Street and NW 47th Avenue.

5West side

This spot is an alternative for spot 4. It is at the parking lot of a company built on former airport property.

6North side

Although spots 1 through 5 will enable you to obtain a nearly 100% score, the north side could result in the last unidentified aircraft being read. Beware that this residential area is not the best of the Miami area.
