Drug Free is the way to be!

We were driving to Kellie's soccer game and we passed by a local high school. There was a group of boys standing in the parking lot and Kellie asked..."are those kids being drug free?" I told her that it looked to me like they were. She responded "well, that's good because that sign says this is a drug free zone!" Now the joke between Jeff and I as we pass groups of teens is to say "do you think those kids are being drug free?"
