On my last couple of journeys, and Inspector (probably older terminology for the job!) has been riding with the driver - checking timekeeping, route-learning possibly...
Yesterday I returned home on a double decker (which I haven't previously see on my 635 route) with leather seats - or are they Old English Vinyl?

- well they were clean and comfortable and it was quite nostalgic to go and sit upstairs again - I think I was in short trousers the last time!
Another bus I used last week, a blue and red single-decker with Bee Network branding (apologies, I'm not up to date with bus types), had extremely comfortable red seats... it's all come as a bit of a shock to find my local bus service is more reliable, more punctual and more comfortable than the Northern Trains service I previously used, and it's somewhat restored my faith in public transport.
