So they drug a blade across a large field and I noticed some old brick sticking out. Spotted one piece of glass sticking out ... nothing too spectacular and wish it wasn't clipped, but you never know where something is going to crop up. No other bottles note, some glass but not enough to indicate a trash pit or dump. Probably just a random bottle dumped with the bricks. It did make me spend about 2 hours combing over the field and I will likely end up back there to look again?!?
