Bat Letterbox  LbNA # 41990

Start at the most fun "frog" in the Greenbelt Park (in the woods by 7 Flags Fitness Center).

Go to the playground and take the left path into the woods.

Pass two bridges. At the far side of the second bridge look immediately under the left side to find the "bat box."

Let us know if you find it. It's our first one.
