I agree that real men (and women) ride in the rain...although I've quit riding in thunderstorms!
What I'm scared of, however, is riding in the DARK in the rain.
It's bad enough trying to ride within my bike's light beam as it is (no Oakley's in the rain, of course), but thinking about all those drivers hunched over their steering wheels, peering through those greasy, rain-smeared windshields...whoa, that really gives me the creeps!
At least we're allowed flashing taillights here, which get drivers' attention better than steady beams. I understand they're illegal in much of Europe.
