If our memory serves us correctly, when there was a smattering of snow on the ground last year the borough council closed off Level 3A of Main Square multistorey car park. The reason being that it was slippery. Given that anyone who wanted to park there must have already driven in traffic on slippery roads, the caution was excessive.
Anyway, common sense has broken out. This year there’s a pragmatic ‘snowflake’ warning to drivers, and nothing more. Nothing more is needed.
