In this video, the owner of this 1817 property was excavating ground for a new septic tank and found a strange discovery. The excavation exposed a hidden tunnel on the property. We were so intrigued about what was down the strange hole, we decided to rig up a camera and a flash light and attempt to see whats inside the hidden tunnel. Plus, we also metal detect the property and pulled up our 4th silver coin from the yard. The permission has been amazing. We've pulled some really nice coins and relics from this yard over the past couple years. Enjoy the video and help this channel reach its goals. Thank you!<br /><br />Update! I was able to explore another tunnel (2 tunnels found) on the property: <a href="https://youtu.be/ZQsvkxGaDxg" target="_blank" rel="nofollow">https://youtu.be/ZQsvkxGaDxg</a> <br /><br />Looking for excellent Web Hosting with your own Domain Name?
