One thing that has bothered me for a long time, is the harshness of 'Natural Justice'.
Even in the hot, tropical southern States of the USA, many of the bridges have a warning sign saying "Bridge Freezes Before Road".
For years I could never resist shouting a warning to the rest of the cycling group as we sweated our way past these signs in 100 degree heat and humidity. There was no malice intended, and I understand the underlying physics, but I simply found the signs in a Florida context amusing.
Fast forward many years and I'm back in the UK. On a winter ride through the Dales I'd spent the day constantly on guard for black ice but a mile or so from home and back at sea level, I finally started to relax. Cup of tea, warm shower . . . shoot . . . I'm on the ground and it hurts! Silverdale railway bridge is not 'skewed', but has a right turn on and a left turn off. Not that I did the left turn as I'd hit the deck and bounced into the limestone parapet. As I staggered to my feet it was obvious the bridge was sheet ice from one side to the other.
To this day I still think 5 hours in casualty, my winter riding clothes in tatters and the bike scratched and group set ruined was too harsh a comeuppance for my very mild mocking of those American signs.
