Not quite winter here yet, just the start of the rainy season...I don't really consider it winter here until the snow falls.
I'm currently acclimating to the colder temps. It hasn't been super cold yet(only 40's,) but the elevation/terrain. makes the temperature kinda tricky to deal with. Almost all of my local rides are above the golden climbing ratio of 100'/mile, so I'm either hot on the ascents or cold on the downhills. Of course I can shed/add layers, but that entails bringing a bunch of extra clothing. To make it worse, my house is basically the high point on many of the rides...so I descend nearly 4000' downhill in the chilly mornings and then climb back up in the afternoons. I just deal with it and recognize that a certain amount of discomfort is just part of the experience.
