if it continues i would build a speed bump...put a 8 inch tall pile of pee gravel or something like it across the road....60mph and speedbumps he might slow down after that!!!!!!! is your road a county road or private road? if it is private talk to others that live on the street and see if they would object to a real speedbump(blacktop,tar)
i live on a street that ends in a culde-sac, this neighborhood is loaded with kids,,, i yell at people to slow down year round!!!!! the occasional tuff guy stopps and wants to run his mouth (never get out of thier cars) but most people slow down!!!!! i know that if one of my kids gets hit , the driver won't need to worry about the cops!!!
