I used to think similarly, but while at the range waiting to see if I would ever get my rifle back; Bill the guy who helps run Chaffee had all his bags labeled in marker with his info. I think if you are frequently at competitions and ranges it would likely be a person like you who finds it. Also you could put a business card with your work address or just phone and email info, some thing to contact you by, not necessarily your home address.

Or a CO-AR15 patch or sticker!!!
