Airplane wings? Some new form of irrigation equipment? Space shuttle components? Pieces of some secret governmental weapon?
I was tilting at windmills.
Which is what they turned out to be — windmill blades, to be precise.
I found that out later at a truck stop in Rocker, just west of of Butte, where several of the oversized loads, having just negotiated the winding stretch of Interstate on Butte’s eastern side, had pulled over for a rest.
According to the Associated Press, the explosive growth of the wind energy industry has led to dozens of trucks a day toting the blades down the nation’s Interstate highways to their new homes, mostly in the west.
Commonly traveling in convoys, the oversized loads haven’t caused too many problems. They’re not any wider than a normal truck, but they are longer — much longer. Some of the blades extend 180 feet, about triple the length of regular semitrailer loads.
That means it takes about three times as long to get around them, but considering the clean, renewable, independent energy they will go on to supply, I’m a fan.
