Want to know something kind of interesting about USPS mailboxes. I'm a by the books type person and I looked into this a bit because I wanted to do something similar. Depending on your mailbox if it's a communal mailbox that **legally property of USPS** then you can't put anything inside, modify, or tamper with it or it's illegal. Many mailboxes are USPS property so this isn't as crazy as it sounds!
