Spring?

It seems like Spring may actually arrive.  Unless it snows again.  The talking heads at the weather channel insist that the pattern that has brought us unrelenting cold for quite a while has changed.  But since there is still 12 inches of the white stuff in my yard and there are mounds 2 stories high in parking lots I wonder if Spring could actually be upon us, especially since there are 2 more weeks of winter on the calender.
