What's the deal with the Wind

I could understand if I lived on the coastline where the hurricanes came in but I am in Indiana and lately the winds are becoming unreal. Days of winds some knocking down trees and causing power outages. I remember some years back we had a real bad windstorm and there were power outages for days.  Winds and yard sales just don't mix and I was so ready to have a yard sale to get rid of this extra stuff on my front porch but now I am beginning to wonder if it's going to happen. Maybe I should just buy a kite instead.  Or hook up some kind of wind power now that's an idea!
