To digress:
If that's a section of the tower for a wind generator -- it's not a "standard" piece. We've been seeing lots of the tower pieces this summer, and most of them are longer than the one in the photo -- and much lighter (weight). There was one in the parking lot of a motel where we stayed in Green River, Utah, last weekend -- and I took the time to get close to it. First of all, this one (in the parking lot) was similar to most -- about 60 feet long and carried on a dual-axle dolly that was tied to the tractor, which also was a dual-axle unit. The load that duals can carry is limited to about 40,000# or less. The photo you put up here shows lots more axles than just five -- which implies heavier than the usual 80 - 90,000# GVW. Ditto the length -- the "tube" itself looks pretty short (comparing it to the rest of the stuff in the photo).
So maybe it was for a wind generator, but for one hellaciously big unit -- not the ones we see scattered over the landscape here and there throughout the county.
