I was just thinking of doing a poll like this but more along the lines of
What seasons do you ride in?
1. Summer only
2. Year 'round in a warm climate (TX, CA, FL etc)
3. Year 'round with a real winter.
4. Year 'round with no real summer.
Personally, i used to ride year round with a real winter (Wash DC) in all kinds of weather. Now in Spokane, WA, haven't hit winter riding yet, so we'll see, but probably will ride so long as the roads are not iced.
