Rule #9: If you are out riding in bad weather, it means you are a badass. Period.
"Fair-weather riding is a luxury preserved for Sunday afternoons and wide boulevards. Those who ride in foul weather... are members of a special club of riders who, on the morning of a big ride, pull back the curtain to check the weather and, upon seeing rain falling from the skies, allow a wry smile to spread across their face" (The Velominati).
