The best thing I ever found is an old medicine bottle from 1858. I was idly stabbing the toe of my shoe into the dirt of a horse stall in an old barn and saw part of an aqua bottle, so I started digging in earnest. Once I had the old treasure in my hot little hands, a barnyard dog howled a warning and chased me through the fields until I made it to the road. I thought the farm was abandoned, but the owners were not officially off the property for a couple more weeks. However, the big scare was worth it because it began a lifelong pursuit of antique American bottle collecting.
