Okay, this feels like a REALLY dumb question.....

So I now have a waterproof jacket with a hood for rain. Ummmm.....how does one orchestrate a helmet and a hood. Either way, hood over helmet, hood under helmet just seems weird.

I also have a waterproof poncho. Do ponchos flap in the breeze and get in the way on a bike? (Remember, I'm a slow paced pedaller so I don't go at supersonic speeds.)
