While walking the mutt, I happened to look at a neighbor turning out at the opposite drive of my condo.
Heard a big THUNK, and saw that he'd obviously had a hardcase up on the roof he'd forgotten about. Went right over to retrieve it, a Ruger Security 9.
I figured that I'd see him later on, and/or just leave a note on his window to come see me.
Sure enough, I walked out in the afternoon and saw him looking in the landscaping and such, LOL.
I shouted at him and he turned around. He began to ask me, and I just laughed and waived him on over. "Yeah, I got it Bro".
