Speaking of windmills. The International Windmillers Trade Fair is now going on in Calhan, CO This is the 26th annual trade fair that is hosted in different parts of the country. Windmillers and windmill collectors and restorers bring in trailer loads of rusty iron and spend 3 days talking, buying and selling. Finding missing parts to windmills they are restoring and showing off restored mills. Last year it was in El Dorado, KS and next year will be in Rochester, MN. In 2016 it will be in Poteet, TX
