I have driven by this sign many of times, but never actually went under the bridge until I went searching for a geocache one day. It dawned on me that this sign has got to be unique to the area, so I thought what if all you had was a picture to go on to find a cache. It seemed like a solid challenge for some local cachers. So, I am going to try it.
The first challenge is to find the image below, once you do this then you can go to the second stage.
The second stage will require you to project this coordinate, hope you have a compass or another high tech device that might help you out. The final cache will be located 1,150 ft. at 302 degrees. Muggle activity could be prevalent on a Sunny Day, but with poor weather you will have no worries. Good luck
