I found another small dumping pit but the only thing worth saving from it was a shotglass or candle holder from glass, and two long glass tubes filled with graphite sticks like the ones inside pencils, really strange.
I spent much of the day looking for treasures but except some k98 ammo, a messkit with bits cut out from it and a small ashtray it was all rubbish for me today. Anyway I had a very nice time and I might have discovered a dumping pit when I was going back to the car, but we ll know if Im right about that another day :)
