I have 3 historic windmills not far from me, but all 3 are located in an open-air ethnographic museum, where I'd have to pay an entrance fee. That said, I know a way to sneak in, but I'm not sure bikes are allowed in there, so I'm also not sure if I wouldn't attract unneeded attention that way. Anyhow, I could possibly get a daylight shot only on weekends, so I reckon someone will beat me to it anyway.
