I usually don't have a problem with the cold. I feel it's my natural habitat. But last week we had a freak 60 degree day, and suddenly I remembered how much easier it is to prep for a ride in summer. No more of this carefully arranging 3 layers and hiding all exposed skin.
Ever since then I started getting annoyed with winter riding, even though I had no qualms until that point.
Also... I'm sick of the wind.
