Well, 2 and 3 years ago, winter was pretty winter like even down here in north MS. Either lots of snow or lots of cold ( by our standards ). Then, last year seemed like Fall at best all "winter" long, sometimes more like real early fall!
But, I was in Branson, MO yesterday and it was quite cold. And I noticed that it was 8*F at Cold Springs, WY!
Wow, single digits 1st week of October. But I have learned you can not make an accurate judgement based on how it starts. But, if I was up there with my hammock, I sure would want some good insulation under me!
