Think I might have answered my own question of what the difference is between snow events 30 years ago and today........ traffic.
It"s all very well plowing and gritting roads, but without the traffic to flow freely along those roads, snow will continue to settle.
30 years ago, there were not as many cars on the road, much easier for traffic to continue moving. Today, with so much traffic on the road, congestion and slow moving traffic causes the very problems that the gritting is attempting to alleviate. The result, in extreme cases, is that cars are abondoned, making it even more difficult to keep roads open.
I think the bottom line is that we don"t have the road network to handle the number of cars now on the road. Maybe we need to rethink our love affair with the motor car ?
Going to lie down now.........
