Good story Miles!

I drove from Chicago to Iowa City in early August mid '80s to ride their annual RAGBRAI (did it twice) in my '66 122s Volvo estate wagon. (loved that car!) I left late on a Friday night to arrive for the Saturday morning start. It was raining in Chicago when I left -
hard. At a certain point on the journey, my drivers side wind-screen wiper flew off! (whoosh - gone!) It was monsoon-level rain and luckily I was able to (as you referred to) pull under an overpass safely. I put the passenger side wiper on the drivers side, waited for a lull, and continued into the rain. Got there in the early AM and snoozed in the car until dawn. I made a fabric covered foam insert for the full cargo space (with rear seats folded down) in the wagon which was actually very comfy to sleep on. I took the bike out of the car when I got there as I was in my friends safe IC drive-way.
Also - I was on a Sunday group-ride on near-north Chicago roads when the temp dropped radically and we (all in short sleeved jerseys) on the way back were pummeled with cold hail! We just laughed as it was so extreme!
Raced (road bicycles) in the rain, won a UCF RR in the rain, and had epic training-rides and centuries in the rain. Those days are over - no more rain rides for Geo...
I've also been on my VFR in the rain here in the Bay Area - at night (!) lane-splitting and having cars attempt to squeeze me as I pass. (door-slamming A-holes) Oh well... chalk it up for life as a dedicated 2-wheeled road-warrior I guess.
