That disc was one of 6 discs, that a group of five of us found today at rosie. GI Dave and miles each got 2 of theirs they had lost in the last week.
That jls was one of 2 discs we found that were never seen. They were stepped on and the person slipped to reveal a disc underneath.
Just so you know that disc was almost halfway to the basket. If there had been no snow you would have totally been over halfway.
