New sticker for showing off UP

In a previous post, I had mentioned that the UP is somewhat unique in that we have our own area code (906). All of the UP is in that area code and only the UP is in that area code. The other day I noticed that one can purchase a white oval sticker with 906 in black so I did. And today someone asked "what's the 906 sticker about," but as soon as she asked, she answered her own question. Just a subtle way to show off where one lives.
