How do I see which routes are being utilized ?

I have a 3640 in my corporate office with a whole bunch of static routes. How can I tell which ones are being used?

IOS doesn't maintain statistics on route usage to my knowledge. Someone can correct me if I'm wrong.

Thank you for the response. I will try to figure out some other way to start deleting old routes not in use anymore.
