Here is San Diego we're in the middle of a 'very rainy' week (3.5in the past two days, and still raining today).

Tuesday night I rode home in the rain with an ikea rain poncho up top, and sandals/wool socks. The poncho worked pretty good (not ideal positioning of arm-holes for cycling, but it kept me dry), and the socks were totally soaked (but not really cold, and waterproof sandals, so it's OK).

Wed morning I rode in with poncho, rain pants, and my riding sneakers in plastic grocery bags (ghetto shoe covers). Waste of effort, it was just barely sprinkling. But through the day the rain really picked up, there was lightning and thunder, and believe it or not a tornado warning! Since my wife was out picking up kids anyways, I wussed out and had her pick me up too. I'll drive home tonight and back to work again tomorrow, my bike will be locked up safely at work the whole time. Fri night I'll leave 'my' car at work (like I usually do, it was home for Christmas) and bike home (probably dry).

I am willing to ride in the rain, but I'm not super eager to make a point or prove something by riding in the rain when I don't have to.
