theres a house in the town i grew up in on a retarded corner, the house got hit 2 or 3 times by crashing cars. so they bought and installed get this, old train tracks cut into posts spaced 3 foot X 6 foot deep and 5 foot up, down the whole side walk ( its a corner house) then added a hedge to cover them up. those rails have saved the house from countless attacks since they were installed lol
