[Tigers] Signs (Non Tiger)

[CoolVT at aol.com]

Up in the mountain area the danger of high wires is for collision  of 
gliders (planes)and human gliders.  But, not sure what good a sign on  the ground 
would do for those 2 situations. Normally they put basketball sized  orange 
balls on the wire for visibility rather than signs at ground level. So, a  
mystery looking for  a better explanation. Mark

In the  last year or so I have noticed the appearance, along Interstate
highways  here in MA, of signs indicating where power lines are crossing  
the
highways.  Now, if these lines were low enough that there was a  danger of a
truck snagging them, I could understand it.  But no, most  of these lines
appear to be well above the road, 50, 75, maybe 100 feet  above the tallest
trucks.  Anything that would fit under the bridges  is in no danger.

Does anyone know the reason for this?  Is this  happening around the
country?  Certainly some sign makers are being  enriched, but is any other
purpose being  served?
