It's thrilling, really, that first moment your defenses are breached, that first trickle of water between your shoulder blades, like a slow, icy tickle on hot skin. Then the rain pants soak through, followed by the slow saturation of wool long johns. Then the neoprene gloves become clammy; they drip water when you clench your fists. Then more water seeps in from your neck line; it creeps up your arms and your waist; your fleece hoodie absorbs it like sponge, swirling water vapor inside your plastic jacket, condensing until there are more droplets on the inside of the sleeves than the outside. When the wool leggings won't hold any more moisture, lukewarm water trickles down your vapor barrier socks to your liner socks, which are already soaked with sweat anyway. You wriggle your white wrinkled toes and breathe in the thick humidity, the vapor of warm sweat and cold air surrounding your own personal biosphere. And you pedal harder into the geyser streaming from both sides of your pathetic fenders, and you smile, because you and the rain are finally one, and you are free.
