M6 Birmingham heading North

Joining the M6 motorway heading North at Birmingham, it doesn't take long to grind to halting progress caused by the conjunction of the M5 and M6. Tedious in the extreme with little let up until Lancaster where spaces begin to open up and driving can become a pleasure, getting even better in Scotland. The reverse trip can be a nightmare as density increases towards journey's end. I'm so glad I live in Scotland.
