Don’t take pictures at 75mph in the left lane of a major interstate highway.
I followed this thing for a few miles before I finally figured out what it was. Care to guess? Give up? It’s a blade of one of those ginormous wind turbines, headed north on IH-35 around San Marcos, Texas. No clue where they build these things, but if Boone is right, it’s headed to the middle of America, where he says the best wind is.
