From about May through September it's so hot where I am (Texas) that spending time outdoors, in the garage, or on a motorbike is just miserable.
October - March is what I look forward to as they are about the only pleasant months to spend in the garage without sweating to death in 90-100+ degree weather. In the winter we only have a handful of days that get below freezing and rarely have any snow or ice, but when we do, it's epic. Remember Super Bowl 2011? Everything except that football game basically stopped for about 6 days straight.
