Growing up it was drilled into us that if u were in danger you could always look for a yellow square with the little house cartoon picture and go there for safety.
It has been years since I have seen a house with the logo.
Haven't seen the ad campaigns about it.
My kids aren't learning about it at school.
I understand that advising kids to go to a strangers house isn't the best solution, but in times of danger u need something.
