Our mailbox is covered in Jasmine, a bee's delight. And though Mac trims it back regularly it grows right back. If I were the mailman/person (whatever) I think I'd poke the mail in with a stick. You can see the front of our mailbox, some of our neighbor's boxes are so covered you can't even see the door. Mac usually picks up the mail because our box sounds so buzzy you'd think it was getting ready to fly off.
