When we were on our way to and from Illinois we saw these windmills. On our way there is was night time and we saw all these blinking red lights everywhere and did not know what they were until our son said they were the windmills. Then when we got close to the ones that were close to the road you could faintly see the windmill blades turning. We loved the red lights. There were hundreds and hundreds of them! When we were headed home it was day light while we were going through Indiana and we were able to see the windmills and take pictures. They are huge and so awesome!
