Centsless, I know it is perhaps silly, but crashbandicoot did make an interesting point about the crescent.
There was a strange family that lived up a dead end holler up the road from me growing up. My daddy told us to stay away from them. They had all kinds of weird signs and symbols hanging around their yard, including a crescent moon turned upside down. It may have just fallen that way from neglect, I can not say. People lived there but you never saw them during the day. You could hear noises from that way at night though. That place gave me the creeps. We had to go by there to a hunting place at times, and we always stepped faster.
I went by there a few years back to show my wife where I grew up. It still looked much the same but run down. And I still got a weird, creepy feeling even though no one lived there then. Like I was being watched by an unfriendly person. Just silly carry over from childhood I am sure.
Good luck digging there. Hope you find some good items. Be careful and take antibacterial soap along.
