Here's one I was thinking of near Ocala, FL, I believe John Travolta has/had a place there:

29.2747779, -82.1204260

And another one in Yucca Valley, CA:

34.1289163, -116.4077455

Whoa. That area has things that look like roads, but are extended taxiways from the homes to the runway. For the early-alphabet taxiways there's a clear distinction between the public roads and the taxiways. The roads end in dead-ends before the runways, and the taxiways end in dead-ends before the roads.

But, when you get to taxiway echo, it actually crosses Spruce Creek Blvd. So, you could be slowing down to a stop sign, only to see a plane taxi across the road in front of you. I wonder how often cars end up on that taxiway by accident.
