my daily journey is about 30 miles each way; part motorway, part through Bradford or Leeds. I live close to the northwest corner of West Yorkshire, in Bradford council area but only a couple of miles from Leeds council area. It's a bit hilly round here. Not up to Peaks/Lakes/Dales or Highlands standards but it certainly isn't flat
Monday this week I set off, got through Shipley to the border with Leeds council area, couldn't get any further, so I came back home & took it as a day's holiday. Tuesday I went through Bradford, got to work in a little longer than the usual time. Wednesday I tried to go through Leeds; got about 3 miles, had to turn back. Thursday & today I went through Bradford – no problem. Is this a pattern?
Both times when I had to turn back, it wasn't because the roads were impassable, it was the queues as far as the eye could see that weren't moving just due to volume of traffic.
Anyway, I'm an IT bod with a company laptop and broadband at home. I work from home when I can't get in – it's much better use of the company's money (i.e my salary) than sitting in traffic when I should be in the office.
