Back in the 60's I worked two summers at a camp in the Adirondacks for educably retarded children..that was the term of art way back then...The good citizens of the municipality put literally hundreds of the big yellow..SLOW CHILDREN signs all around the neighboring roads...When the first parent visiting day came, the uproar was both HUGH and SERIES..
--there were state-required "Children Crossing" signs at the school I mention above which were protested by the students there, also---
