I went solo this weekend for a few hours. I thought all of my buddies were on a road trip farther North and I had to get out. I wrestled with going out up until the last minute loading up the truck. I'm glad I did. I found six buttons including a Cuff Sized 1814 - 1821 Eagle and Cannon Artillery Corps button. It's so tiny and beautiful. I also found another 1821 - 1830's Eagle A Coat Sized button that's toasty but it's a different backmark again. I have now dug three of those at the site and all three have different backmarks.
