Honestly, once I have purchased everything, Ill probably bail below 10f, as im a big baby. Who knows, once I get going in the winter, I may love it so much I can't stop riding. Its likely a couple months off before it starts getting really cold in PA, so I have time to get all the stuff I will, need. But its good to know that some of the stuff I have, will actually be of use.
Wool socks really the way to go i assume, as I keep hearing people use them. Though, the gortex could come in handy as well.
