With the exception of unsafe conditions, riding in all weather is a blast. Though I don't know if I'd think so, if the weather included 100+ degree heat. And I'm fortunate to have terraformed my riding conditions through years of refining my route. I'm of the opinion that route choice is the #1 safety factor for cycling.

Granted it's not for everybody, but the extremes and unpredictability are actually part of why I love the great outdoors.
