There are only ever two occasions when I will ride in the rain. The first is my commute to uni and the second is when I'm getting paid.
Any other time I just don't bother, I barely enjoy my solo rides at all let alone a cold and wet solo ride. Everyone has their opinions and I know people think that if you love riding then you'll ride in any weather. I don't buy into that though. Maybe I have feline attributes or something, but rain can do one.
