As a cub scout I did the same thing, with similar results, just on a smaller scale. A couple doors down from our house, the road made a 90° turn north. You couldn't see 'through' the corner, and plenty of kids (myself included) played on the street. I hand-painted a Slow: Children at Play sign, and asked permission from a neighbor to put it in the parking strip in front of their house (they were on the corner). Before too long, the city installed an offical one.
