Our route meant that we ended up going through the middle of Coventry just in time for everyone to leave school and the middle of Birmingham just in time for everyone to leave work, but all the filtering was worth it because we gained a whopping four landmarks.
The first of these was a short walk along a canal from the nearest road, enlivened by watching two narrowboats sort out which of them got to pass under the bridge first while a moorhen paddled frantically out of their way.
Our second landmark was a tourist attraction with its own car park, but we had difficulty finding the structure itself due to dense surrounding foliage. Number Three was located in the middle of a roundabout and so vast I spotted it from almost a mile away - the difficulty here was finding a safe place to park so I could take a photo of it and my bike.
At last we left the ring roads and suburbs and rode out into the country in the direction of Sutton Maddock. We missed the signpost for the hamlet we wanted - it had obviously been designed for a time when traffic passed very, very slowly in a horse and cart - and doubled back to find a leafy, single-track road leading up to a church. Hurrah!
Even if a landmark is easy to find, getting off the bike, setting up the shot and taking a photo eats up time - and often they're not easy to find. Over gammon and chips just inside Wales, with half an hour's light remaining and another landmark in the area, I pleaded enough. We made rapid progress up the motorway and the twisty B-road into Heswall.
We arrived at our hotel dead beat at past ten o'clock to find a live band in full swing and the bar full of the local youth. But it would have taken more than a few dozen drunk teenagers to keep us from our well-earned pints.
