I fly out of Addison a lot. I am also friends with the A&P located at Airpark. A few things to remember when operating out of airpark:
The runway is maintained. But, it is not perfectly smooth. Treat it like a soft field.
When taxiing anywhere besides the runway, you will be taxiing on turf. Protect your nose wheel.
In the daytime watch out for chickens.
At night, beware of coyotes.
The runway has non-standard markings
The runway is a lot shorter than you think due to displaced thresholds at both ends due to buildings, fences, and trees.
The runway is aligned with the runway at Addison. You will be on a very similar final and departure leg.
Addison is only 3 miles away. You can almost see the Airpark area from the Addison tower.
Because of Addison towers Proximity to Airpark, contacting them as soon as practicable means as soon as you start the engine.
non-standard markings.
