> the political signs you see on the side of the road make excellent
replacements.
Two thoughts here.  First, most of the signs here are corrugated plastic.
Will there be a heat problem?  I know that those signs left on the ground
deteriorate pretty much in a year.
Second- although it is illegal (in VA) to put signs on the side of the
road, it is also illegal to "steal" illegal signs from the side of the
road.  That is why I volunteer with, "Adopt a highway", it gives me a
permit to remove these signs.
