The forecast was for a nice Washington, DC summer geocaching day: mid-80's (F), no rain or thunderstorms, and manageable relative humidity (70 percent). So, I hit the road about 1100 to pick up a few Maryland caches that were rained out from the 4th of July geocaching trip.
This cache is located in a very large regional park, not far from Washington, DC and just a few kilometers from Northern Virginia, across the American Legion Bridge (which carries the capital beltway, Interstate 495, across the Potomac River).
