A lesson here. Buy trip insurance every time! These people are out many thousands of dollars each without it.
The Raleigh paper today stated that the line was noted in the plans but not at the site............... So whose fault is it now? Even in my neighborhood there are warning signs where even a telephone cable (remember them) crosses a road or whatever. Admittedly the signs could have been disturbed in earlier phases of the construction and unknown to the media hyping it up.
