And I reminded myself... I still haven't found a source for those darn reflective buttons. I had a sign in mind, but without the reflectors...

They are extremely hard to find.
I'm STILL trying to find a contractor who will still make the button-type signs, at least one type. (There are several different types of the 'buttons'.)
For the BGS, it's easy, since the sheeing reflective still isn't that good for large projects like that, but for smaller road signs, it just isn't done anymore.

<shrug> I'd like to get a few made with the buttons as well.

Me.
