I love to see those. It tells me what area to avoid in an unfamiliar area.
Well, you dont really get that beneft if I its a freeway/expressway. San Diego solved the MLK Boulevard issue by naming a freeway after him (the locals dont call it that, racists that they are, they refer to it as the 94). That way residents/businesses dont have to deal with changing addresses, etc.
Absolutely!
Anytime Im in an unfamiliar town I can always tell what neighborhood to stay away from by finding where Martin Luther King Blvd/St/Rd/Way is located.
