Big machines have been rolling up to Allegheny Mountain for days. Site development work on Virginia's first industrial wind energy plant is expected to start this week. Passersby report heavy equipment has been parked near the entrance to Red Oak Knob, and blasting heard over the last couple of days. A skidder moved in after dark a few days ago, and trees are being cut near one of the turbine sites; one truck full of logs has already headed out with its load.
