I'm posting this in religion since the situation has religious overtones and could as easily involve the name of a church as not.
First, I know the U.S. Post Office is a hybrid organization, part public, part private, but it does utilize our tax dollars.
Second, I know rural mail carriers use their own vehicles and are entitled to post bumper stickers, etc., for anything they wish--I totally support that.
What I'm speaking of us a vehicle I just saw on Hwy. 72. The SUV sported a magnetic sign, large, and in official-looking red and white lettering: U. S. Mail. in the SAME sign was a logo for an organization. I would think even if the mail carrier paid for this sign with no total or even partial reimbursement, this is illegal.
