You are looking for a bison tube a little smaller than a matchstick holder. It will be off the ground because the area floods
This one should be a simple park and grab if you have ran into this cache before. It is located in an area of a local park and as you can tell by the gates, the bridges wash out often. As a child I used to wade down the creek chasing fish and frogs. Thise days are long gone due to clutter and pollution. About a year or so ago the water got to rushing so bad it actually pulled off asphalt and carved it's way through the base of several wooden poles. You will not find this cache on the ground.
