75 degrees and Sunny - but wait, it's March?

The last few days (weeks/months) have been unseasonally warm. The springs birds are back, flower are blooming, trees are budding and the bees are out in full force looking for food. But it's still the middle of March. Isn't supposed to be cold still? But then again this entire winter season has been extremely mild. Upon moving to Wisconsin everyone warned us of the sever winters...I think we got a maximum of 11 inches of snow and just a handful of weeks were it was cold enough to freeze the ground. Sure, it's been great not having to deal with the snow and cold, but I kind of feel like we have completely missed a season. I guess we'll see what's to come.
