Spring, Midwest = Storms....
Yeah I know, I already heard on Weather Channel "Massive storm outbreaks, global warming the cause" etc.
Just sitting here scratching my head. Uh... I look forward to spring EVERY year for this stuff.
Thanks, Lurker. Just waking up in the storm zone here. I don't watch local or network news so I could have been utterly oblivious until the sirens started going off, as they did the other day.
Have a good day!
