Seen a few Blue Northers down around there where the temp went down into the 30's and I'd swear it was more uncomfortable than MINUS 30 in Montana.
Probably all those **** big bugs freezing and hitting you when they fall.....
My daughter moved to Wisconsin, a few days ago it was -8°, and she told me yhe same thing, that it seemed colder in Texas, the days it got cold.
I can attest to this! We almost moved to Idaho years ago, when we went to visit it felt so great... but it was in the teens and snowing. We came back to 30s and rain in Atlanta and it just felt SO cold here.
