I did it!

I was walking throught the Costco parking lot a few hours ago and a lady drove by me with a baby in a sling/infant carrier strapped to her chest as she was driving! Her window was down so I yelled "Your baby would be a lot safer in a car seat". I saw her give me a dirty look and mumble something as she drove off. Well, I tried. Thanks for whoever lent me some...guts.
