Modernaire Apt Complex 2393 Cardinal Drive, apartment building On Wednesday evening, July 29, 2020, I found our group mailbox door not locked properly. Very unsecure. This has happened twice before that I have seen. I wrote to you about this previously. If there is a problem with the mailbox itself, then it needs replacing. If it is a carrier substitute, then they need to be reminded because our regular guy has always been very good, very conscientious at his job. Mail security is already getting to be a hot political issue this year. We just want our vital mail to remain private and secure. Thank you.
