Walking down Eat Capitol last weekend we noticed many houses had ornate weathervanes attached to the top of their crows peaks. As soon as were noticed one we soon started seeing them everywhere... Weathervanes are used for showing the direction of the wind. Atop turrets in Capitol Hill a “true” reading would be hard to get. In order to work properly a weathervane most be located away from other buildings, trees and other objects that could interfere with the wind. If used properly a Weathervane could help a you make simple short range weather predictions. It’s safe to say the ones we saw were put up for decoration only. Not that we can blame the homeowners – there are tons of styles to choose from - in ever conceivable price range. Now that we know they are out there we see them all the time. It’s hard to believe we never noticed them before.
