Thank you!
Research and patience and a whole lot of luck. Todays handful of buttons and buckle came from an unmapped cellar we stumbled apon going from 1 cellar to the next. We trekked thru the woods instead of using the old road. Ran out of time today so will def be back.
That other handful of buttons came out of a 8x8 area. I let a friend jump in and I did a loop and came back and he had 15 buttons all from the same 8x8. Its some sort of dump. About 40 buttons came from it and I'm guessing theres more.
