Instead of defying those baseball bat-wielding teens with a mailbox filled with cement, just try and make it way less fun for them.
We got that one solved. Don't tell the mailman or the power company. And don't worry, a couple of nails at the top are holding that power line in place.
When the latch wears out you can buy a new mailbox, or you can glue in a harddrive magnet to hold the flap shut. Should be fine as long as AOL doesn't mail out anymore floppies.
This was in front of someone's house in Slidell, LA.
Duct tape should fix it.
