Hmmm Rose coloured snow goggles or memory loss.

Being born in 64 I did not witness this so a quick check online to see if a Country still recovering from a war 20yrs earlier was really so better prepared than that of today,

"Another exceptionally harsh winter, the “Big Freeze of 1963,” brought similar disruptions to transport and infrastructure (comparing to 46/47). Snow cover persisted for weeks, with depths reaching up to 20 feet in some areas. Temperatures dropped as low as -21°C, causing widespread damage to buildings and infrastructure. Transport networks were crippled, with roads impassable and many railway lines unable to function.

The severe weather conditions also led to powercuts and disruptions to essential services. The winter of 1962-1963 was particularly harsh in Scotland, where some villages remained isolated for weeks due to impassable roads. The cold weather also caused the sea to freeze around parts of the UK, including the Thames Estuary, the Solent, and the Mersey Estuary, a rare and dramatic event causing significant disruption to shipping and other maritime activities."

"Winters such as 1946, 1962, 1978, 2009 and 2018 all had a significant impact on life in the UK. The widespread disruption caused billions of pounds in lost revenue and highlighted the need for the nation to be better prepared for extreme weather events."
