Woo-hoo, I had to put in the last 30 miles for '05 to make 1,300 miles this year. It just so happened that it was raining the entire afternoon here in L.A so I did my first wet-weather ride. I learned a few things today: I'm really glad I put fenders on my bike a few months ago during the dry summer; leather gloves + water makes them very, very slipper and then they fall apart leaving black dye all over your hands; sunglasses get splashed with water then fog up making them practically useless; cotton socks absorb the really cold water and keep your toes numb.
My only real problem were my toes. How do I keep my feet dry and warm in the winter rain? Everytime I rode through 4+" of water, it would splash to the sides of my fenders and drench my feet. My toes were numb and clammy by the time I got home 2.5 hours later.
I was funny watching the reaction of other motorists as I rode by or waited at a stop light. They looked at me like I was nuts as the rain poured down. Then I realized I was riding around with big grin on my face as it rained. Some people will never understand the exhilarting feeling of fresh air and being one with nature.
