@GoOilers2019 : I have used those outside mailboxes at the Walnut Post Office. I wonder how anyone is able to break into them, and yes, I know they get the mail from the back as I have seen them taking the mail out, but surely they must be pretty tough to open. When people do things like stealing from outside mailboxes that are in plain site, either they are easily opened, or there is no traffic that time of day. Now, we have to park and go inside the Post Office, which is not that much trouble, but the outside boxes were convenient.
