The Montgomery County Airpark is open to the public, even the earthbound non-aviators. You can stand and watch the planes, or go sit on the patio at the Airpark Café. It's a fun way to spend an hour or two, especially if you bring a book...let's face it, staring at the runway without interruption for that long would be a little tedious. But it's more of an entertaining backdrop, the way you would watch people at a sidewalk café. Of course, if you really like aviation, visiting the airpark will be much more engaging, but even if you don't, it's still a nice way to spend an hour or two.
