And a special mention for Harwich: greeting Dutch cyclists with a cycle route sign pointing across a high kerb and then an unnecessary 2½ mile detour around the headland on steep bumpy bramble-infested cycleways and narrow painted footpaths before joining unreconstructed B roads and back roads anyway... Well, it might lower their expectations appropriately but it's embarrassing!
Harwich is terrible. I've only cycled there twice, both times coming back from cycle tour in Netherlands and the contrast, rough badly repaired, potholed roads. It takes less than 5 mins out from the ferry port and I'm thinking our roads are a National Embarrassment. That said, might be the contrast after couple of months cycling in Europe has affected my expectations. Either way makes you appreciate yet another factor discouraging people from cycling.
