April Fools?

So I am assuming our ward young women did this tonight. And I am assuming it had something to do with April Fool's, but maybe not. Ray and I are are pretty unobservant. Our friends had just left not 5 minutes before, I was just logging onto my computer to start a shift at work, the doorbell rang and I heard Ray say "What the heck?" Then he came upstairs and told me to look out my window. The 2nd floor window which overlooks our front lawn. Covered with these paper plates on popsicle sticks, some with cute greetings and some with cute pictures. Kinda funny. I told him to take a picture and while he was doing that one of our neighbors stopped and asked why we had put those all over our lawn. Thanks YW.
