"He who marches out of step hears another drum." ~ Ken Kesey
Not trying to diminish whats happening in the alley, but you don't normally relate Minneapolis or the Carolinas with tornado season.
In 2010, Minnesota had more tornadoes than any other state with 122 tornado reports.I'm originally from Oklahoma and we had a tornado wipe out a shopping center down the street from us in the 70's when I was a kid. I'm beginning to think tornadoes are following me.
I was on the phone with Donnie Miller from Miller Graphics in Wanoka Ok the other day and he said...."I think that is my trash can getting blown around out there". Couple minutes into the conversation he says. "Yep. my trash can just went down the road". I think they just got high winds catching the back tail of the tornado's.
