Ken makes a very valid point.
Tires don't grip so well when the temperature gets close to or below freezing and you do need to stay in one piece so you can ride the next year.
On reflection I've done some dumb rides in the winter.
I recall taking a trip from Los Angeles to Portland Oregon (1,000 miles) maybe fourteen years ago (was it really that long ago???) just before Christmas. I had to avoid the mountain passes by taking the coast highway. The storms that route had been especially bad the whole month previous and I managed to sneak through the one or two day window before the next one. It was a miserably cold ride, camping in freezing conditions, having to warm my hands after packing up in the morning... and then it was fairly nice. So I decided to ride one of my favorite roads into Portland from Tillamook. Filling up in Tillamook, I discovered my favorite road was closed due to snow and had to backtrack 40 miles to a lower and more southern pass. The next day I awoke to snow on the ground!
At that point I took a serious look what why I ride - and the conclusion was that I LOVE IT. But I wasn't fond of freezing my ass off and worrying about black ice. I realized I had nothing to prove - to myself or anyone else - so why do such crazy things?

As for my mileage this year... my LS is the ride of choice when the weather is halfways decent - but I don't think I kept very good track. I'd guess 4,000 miles going into eastern Oregon and day trips, besides errands around town.
The 77RS saw a trip to the bay area - roughly a thousand miles round trip, besides foul weather trips around here. So it's probably seen two or three thousand miles. BTW, that trip to the bay area (for Darryl's Surf City Tech Day) was a pretty nasty one, raining and miserable most of the way there. And even though the weather was great for the return trip, it wasn't much fun nursing a bald rear tire 500 miles home. If any of you run into a situation of needing to made a bald tire last one more day - I've got the tech for you!

But it's no fun - one of the tricks is going slow. Imagine what it's like having the semis pass you up hills.

For me, it's not the number of miles but the quality that's important.
