Someone cocked up and the ticket page hadn't been set live before I had to leave to catch the train.
I've been looking to get a new pair of cheap/basic binoculars for a while as large parts of the rubber bits on my old ones had degraded and become very sticky and unpleasant to hold. Wex Photographic in Norwich had exactly what I was looking for, so I got off the train at Diss and biked the rest of the way in a very indirect route through the countryside. Home delivery would have been easier & cheaper but nowhere near as much fun.
While sat in the sunshine by the River Wensum with a pint waiting for the train home I checked and found that the ticket sale was open so booked a ticket for Manchester and then the hotel so a very successful and enjoyable day.
