Things are changing, perhaps inevitably, with less stewardship for the properties we hunt on; or so it seems to me.
Maybe I'm misinterpreting your remarks, but I see MORE interest in collecting spent shells than in the past. Stewardship with regard to spent shells seems to be improving. For the record, I'm like most on here. I try to pick them up, but don't get them all and try to pick up a few left by others as well.
