Because I found this one while looking back & deleting, and thought it was better than the daylight one of the same spot - Northgate in Lincoln, the Roman wall.
And this is Lincoln's Eastbridge, viewed from the water walk. If you walk up the High Street, you may not even realise that there's a bridge - that timber-frame building there is a cafe, and you can't see the water at all, on either side.
Just above Steep Hill, which is the road to the left. Just here is where, at night, with a light rain, I saw a young man, unhelmeted and with his legs swung out to the side for balance, careen down the cobbles on his bike. I just stared.
And here is the sight that you meet just after getting off the train in Cambridge. Bicycles are locked everywhere--every set of iron railings has at least one layer of bikes chained to it, sometimes stacked vertically, sometimes horizontally.
