My mailbox has been taken out twice - ran over. We are on a straight road with no turns nearby so I don't see how they hit it. I think it is in purpose. I am going to replace it but am wondering the laws and potential liability of making it stronger. I have some ideas that would be darn near I destructible but I don't know if that is a good idea or not. I was thinking maybe 24" heavy wall pipe set 8' or so in the ground with the mailbox inside the pipe and the whole thing filled with concrete.
