The weather has taken a serious dip in temperature recently. Yesterday was bad and today was downright unreasonable.

Normally, I would just hang up the bike and call it a done commenting season, but this year:

1) the weather has turned cold way to early
2) I'd like to continue biking for as long as I can before the snow comes.

I need to buy some clothing, but wanted to see if anyone had any advice/suggestions/best practices for low cost/proper/comfortable options. Any advice, as always, will be appreciated.
