We stumbled across this old bridge by pure accident. We were out picking up some Geocaches that were "On our way home" and the kids needed a B-line home for the restroom. At first it appeared as if the road was going to end in a corn field but once we continued on we found ourselves on this old Bridge. The top of the bridge was lined with solar lights but we crossed it during the day so we're not sure if they work or not. We will Definately have to check it out some evening! If they do in fact work this would be an Awesome night time cache!
You will be looking for a magnetic hide-a-key. You will also have to supply your own writing utensil.
Update: The bridge is lit up at night which is a sight to see! Also make plans too stop by around a holiday and you will get to see the bridge decorated!
