Gore, like Map said, it sounds like you handled it well. Gotta do it. Like fatdaddy said, you need to be informed on the law. Gotta do it.
I've never been pulled over, but I live in a relatively small place. I do on occasion walk up to any law enforcement agent I see, introduce myself, ask their opinion on MABs, and give them a card for this website. (Hello if you're here!)
