This fine document serves as the master copy of where private airplanes may land within the US for customs clearance purposes. It is delightful for reading on paper, but not helpful for geographical flight-planning purposes. Say, this humble canadian wants to visit the Shenandoah Caverns: where best to land to clear customs? Good luck answering that one by just looking at the CBP document, unless you have an encyclopedic knowledge of towns within a few-hundred-mile radius of any random point.

As I have found no other web site with this data, I’ve started a wee google map where some of the CBP-staffed airports are graphed. The map is currently open to public edits, so is just aching for a transcription slave to fill in the other airports and contact info. Please help! I hope eventually airnav.com or ourairports.com or runwayfinder.com or some other aviation-oriented community database site, or even the CBP itself (gasp!), will supplant this.
