I was over near PDK yesterday and decided to take the camera for a few shots. It's been maybe a couple of years since I stopped by. They've really done the place up. The venerable Downwind Restaurant is still there of course, but the airport has built a park right next door to the restaurant. It's fun for the whole family. A playground, bathrooms, shady shelter, and an observation platform that gets you above the fence for photography, right at the intersection of RWYS 16/34 and 2L/20R. Parking is free, and you won't want for activity: PDK is the 2nd busiest airport in Georgia after Hartsfield-Jackson.
Here's the park area, as seen from the platform:
And a half-decent aircraft photo from the platform:
The weather turned pretty crappy pretty quickly so the photos aren't that great. But if you want to see the rest of them, they're here.
