Meh,
As long as you dress up and take your time it's not all that bad.
I walked the dog for 45 last night and was warmer than plenty of random september/october days when I take the dog out.
Just got back from another 45 and it was refreshing. Started the spare car, took it to get some milk, back home. Going to go to costco, hoping it'll be quiet due to he cold.
Edit: maybe I didn't quite get the thread right
It's so cold that. . . I have frost on my newly installed floor around the baseboard in the middle of my house! Wait, WTF, god damn stupid house. I swear I'm going to have to pull this dump completely apart. Probably another area that the builders forgot to put insulation in.
