Killer Ideas for Prom Invitations

My son Benjamin has been dating his girlfriend, Hailey, for over a year now and it's so cute how he still makes an effort to ask her to go to their high school dances.

Prom is May 9 at Naches Valley High School. This time around Benjamin put together a "CSI" scavenger hunt complete with a chalk-lined sidewalk victim and a flower pot murder weapon.

What's a clever way to ask a girl to prom?
