I can't tell if that one is as big as these

That were one of several wind farms we passed near while traveling back from Algonquin, Ill. to Ohio last year. We took the more rural routes to avoid Chicago. Down Rt. 47 in Ill., we saw wind farm under construction such as these pictured and it was quite a site. We passed by the pictured ones while heading into Indiana where we picked up I-65 south toward Indy. Along I-65 north of West Lafayette, we saw another. We'd taken this route several times over the past 5 or so years and not noticed these structures so they must have sprung up fairly recently. Strangely, very few that we saw were actually turning and those that were ran very slowly. As a kid, I remember farms with their own windmill structures that I guess were used for grist and such. So, you made hay when the sun would shine and flour when the winds blew.
It's a tall tower, if I recall 110ft.. As seen from the road when I took the picture. That's at least 200yds away. I'm sorry the picture seems small but in real life its bigger for sure. Use your zoom to get a better view. I hope to visit the neighbor and get up close and provide more solid details. For now, this is it. BTW, it the biggest wind generator around that I've noticed. Importantly, he's not the only one. adios -----Willy
