Update: I dropped it off with my insurance agent, and they are going to work with the other insurance agent to return the papers to the owner.
Coincidentally as I was running my errands a story came on the radio about car thieves stealing papers out of people's cars to get personal information -- name, address, etc. And they are usually striking when people are inside a movie theater or restaurant or something like that.
I used to white out my address from my insurance cards but have gotten lazy about it recently. Maybe time to start up again.
