I would love to see all your finds in one place. You have quite the collection I'm sure. You are lucky to be living in a place with such amazing history right beneath your feet.
Another excellent find @galba68 - one wonders how you keep pulling it off, and also one wonders about why the good citizens of the area you cover kept dropping their coins.
Love those "dirt action" pictures! If you feel like it, raise the camera once in a while to give us a peek at the landscape, too, just for fun. (Not in enough detail to reveal your sites, mind you. I'm just curious for a general sense of what some of the sites look like, is all.) Your finds are exciting.
