Take a walk through a great family park near a part of the city dedicated to sports. It is large enough that it usually isn't overly crowded.
There is room for only the smallest of trade items in this small metal camo-ed container and you will need to BYOP (bring your own pen). You can slide the base from the lid or remove the entire cache as it is velcroed on.
Congrats to Buckshaw Cowboys for being the FTF!
