Thanks, Divingbiker!

I thought of a helmet cover but then wondered how that configuration would keep rain from running down the back of my neck! Fortunately with bike/bus comnmuting there is always the "next" bus if the rain is heavy or I can wait it out in a bus shelter and would never be in rain for long like the hardcorers here.

I'm looking forward to cooler weather but notice that even in the summer if I'm going fast (up to 15 mph....my version of fast) the wind factor is significant and add COLD air to that.....well you see why I'm shopping for jackets/coats/gloves/etc.
