Windmill next door - NOT amateur radio

We are very lucky to live next door to a windmill that is nearly 200 years old. The sails usually turn when the mill is open (Thursdays, Sundays and Bank Holidays Easter until late October). We can have breakfast in our kitchen looking on the windmill and tell which way the wind is blowing by looking at the sails. The photo shows the windmill last evening just before dark.
