Date: Friday, 9 May 2008, 11:44 p.m. Recently I have noticed BOTH a red and blue disc, about the size of a nickel, and placed on the outside of my mailbox. They are relatively newly placed. They can be removed but are stuck really well. They are reasonably thick and would weather well. They are not just paper. They are reflective. I live off the main road, and I drove to town tonight carefully eyeing all the mailboxes along the way. The vast majority had yellow discs, which are reflective, and show up well in the car headlights. As I got into town, I noticed some larger colored discs on the curb at several houses. I would imagine they could be placed on door posts as well, or most any hard surface such as a wall. Go outside at dark with a flashlight and check it out,and see if they are in your area also.

I just got home and did some searching on google, and this is what I came up with.

I was driving home from a meeting this afternoon and started looking at the mail boxes along the road. I saw one with a BLUE dot. One with a RED dot. 2 with mulitple dots... ORANGE/YELLOW/BLUE and another TAN/WHITE/BLUE.

Maybe everyone should check their mail boxes... just in case. They are about the size of a nickel/Quarter.

Has anyone else noticed these colored dots on mail boxes or the posts?
