i run into this some as i work with the DOT here.
i see some folks point, as i have always had a problem with any kind of forced annexation or condemnation procedure.
however, we've also built nice improved country roads with these little unpaved bottlenecks in them where mr. so-and-so wouldn't sign the right of way agreement. i guess it depends on whether they're taking all your front yard or just part of the edge!
also, occasionally these same guys are the first ones to call and bitch becuase there is ice and snow still in front of their place because of the tree canopy or they can't sell the old homeplace because "the road never was finished in front of it".
the DOT needs to be sensitve to peoples land rights and on the flip side, people need to take appropriate action in communicating with the engineers, local politicians, grade crews etc.
killing someone over a road job is a hell of a way to waste their life and your future. it just isn't worth it.
i don't know but i suspect that the guy is either just a nut and they should have anticipated his reaction (never assume you can pull an andy taylor and just walk up there) and some young engineer/supervisor on a power trip probably added fuel to the fire with some arrogance. any more info?
