I was just at the range shooting an improvised paper plate rack. When the guys two bays down left, I of course went to see what they'd left. I only found a few pieces of brass, but also found a pair of prescription glasses. I picked them up figuring I'd turn them into the on-duty RSO on my way out. A few minutes later, I heard a car arriving that sounded like it stopped at that bay, so I stopped to see if was those guys back looking for their glasses. It was. I mentioned that I'd picked up their glasses while looking to see if they'd left any brass, and the guy thanked me for finding his glasses and said they'd picked up all their brass and thrown it in the trash can, saying it was mostly factory 9mm and .38spc. You can guess what happened next. The trash cans at these bays are 5 gallon buckets...so it's not like I was rooting around in 50 gallon trash cans.
