I prefer the old ones, preferably high up on a wall, on a high post etc., where no little excreta bags can deface them with spray paint/ permanent marker.
If it's not cost effective Niall and the newer ones have to remain, why don't the highways department put them on posts? then of course put anti-climb paint/electric fences around them..!
you can see I've got out of the wrong side of the bed this morning!
I agree, I dont care if they are new or old style, but PLEASE put them up where they dont get scribbled on or hidden by bushes or what not and please put them in the same place every time. Trying to get around this city without causing an accident is often a nightmare. Furthermore, why is it that main drags are frequently not signed for miles and miles. You think to yourself..."am I still on Commercial Road ?" or wherever, but try and find a name - no chance. You are supposed to KNOW.
