I was riding my 4 wheeler with a buddy at a local ATV area by the lake and saw a backpack on the trail I thought about picking it up and turning it in, but figured it fell off another 4 wheeler and the owner would soon notice and come back for it. When we pulled up to the trailer a young guy on a dirt bike rides up and yells "hey mister you lost your backpack". He had seen me stop by and thought it was mine and handed it to me. I looked inside to see if there was any owner information and there was a locked cell phone, a baby Glock, and many other items. Things bounce a LOT on a 4 wheeler and I would really be nervous with a loaded Glock bouncing around in a bag with other stuff. I told him to ride straight to the park entrance and turn it in and tell them there was loaded gun inside, which he did. An OKC police officer was driving by a little later and I flagged him down and told him about it and was going to check to make sure it got to the rightful owner.
