New Caution Signs for Utah

In my last post I talked about the procession of cars that can be seen going to and from church on Sundays in Utah. Well that has been replaced in my parents neighborhood with families walking because they built a church at the end of my parents street. Now every Sunday morning and afternoon you get herds of families going by the house and I really, and I mean really want to put one of these signs in front of the church..........

Does anyone know where I could order one?
