On an early morning bike ride today, I found a BIG set of car, house keys on the road. The keychain had 2 different GM keyless entry do-dads on it. I picked the keys up and took them with me. What would be the best way to get them back to the owner? I was thinking about placing an add in the local paper's lost & found section, saying something like: "Keys found, call 555-1234 to identify and claim". Maybe take them to the local police dept?... What would you all do?
