This is a small airport cache. It is straightforward cache in the form of a lock-n-lock box.
There are miles of bike trail here to be explored by bike or foot. There is also small wetland reserve nearby.
Our family has taken up a tradition of visiting small airports and their cafes. We have visited about 8 so far. Some have a great deal of character and interesting suprises. This small airport has a nice restaurant where you can sit and watch the small planes come and go, and a population of raptors in the area.
If you have the chance please visit the Arlington airport where you will find a superb air museum that few know about, featuring many WWII planes.
