The great thing about being an explorer/wayfiner is we don’t all have to agree. I am on the side of a neighborhood signs can be eligible. When I come across one that I think fits the criteria. I will give it high marks. When I see one that doesn’t, I vote accordingly as well.
We interpret the criteria based on our own biases and previous experiences. As well as what is generally accepted in your local area.
Case in point - German trail markers. I would have been on the total wrong side.
I would say, if you feel neighborhood signs in your area meet the criteria, then vote for them. It’s what I’m going to continue to do.
