I was about to have a go at your for describing autumn as 'fall' but see you are 'over there' so will let you off
Low temps don't discourage me from rides or commuting, just a couple of degrees above freezing is fine and even a couple of degrees below freezing can be very nice when the air is dry and still
One winter several years ago we did have a very cold spell (by our standards) where it stayed around -10 below freezing for a couple of weeks continually. The side roads just never thawed and the compacted snow just got polished up, even the main roads which were gritted would turn to slush during the day under the wheels of the passing traffic but then refreeze into a lumpy, rough surface again overnight. I continued to do my 10 miles each way commute by bicycle throughout and would laugh at the terrible tales of extended, bumper-to-bumper hellish commutes of the people that continued to try and drive to work
From the Met Office:
8. Autumn and Fall
We typically think of 'fall' as the North American version of the word 'autumn', but it was in fact in widespread usage in England until relatively recently.
Originally a shortening of the phrase fall of the leaf, the phrase was common in England in the 17th century.
The word autumn entered English from the French automne and didn't become common usage until the 18th century.
