The other day I was taking this road trip to this lake

While we were driving, we drove past this train that had these propeller type things on it. I thought it was awesome. Apparently they were what they used to make the pin wheel things that make more energy. I had no idea they were that big. I only ever saw them from a distance so I of course thought that they were smaller. It makes a lot of sense that they would be that big. I guess I wasn't thinking about it enough or something to that extent. I can't wait till the next time I see them and I can observe hoe large they are again
