I used to have a cache very close to hear, that went missing twice before I finally gave up on it.
You are looking for the replacement for that cache. It is a bison tube hanging near what used to be a Cattle underpass, or cattle Bridge.
Cattle Bridges were very common up until the 1940's, when farmers needed to move cattle from one side of a road or train tracks to the other without disrupting the flow of traffic. They are typically concrete or brick tunnels, used to link fields. This area is now covered in homes, but was once a bustling farm commuity and cattle bridge's were quite common. Several examples can be found along the TH&B rail line, which is now the TH&B hiking trail that you are standing on.
Please bring a pen or other writing instrument to sign the log, and replace the cache as found.
