You all seem to have seen some very different fens to those I've seen, yes I need to use some busy roads for access, but equally I can ride for hours without seeing a car on some roads on some days
My commute home from Cambridge last week for example was very pleasant
- across Cambridge avoiding the tourists along the river, and the cows blocking the cattle grid
- get passed by two cars and a cyclist between Fen Ditton and the Quy Mill Hotel
- get onto the really nice cycle path past Anglesey Abbey
- One arsehole driver between the end of that to where I left the main road at Swaffham Prior
- 3 horses, 5 cyclists and a tractor on the back lanes between there and Wicken Fen
- back road from Wicken to Ely and up the river bank, one dog walker, one runner
- Through Ely, I didn't die, nothing fell off or broke on the bike (I've never so much as broken a spoke in 19 years living here)
Lack of suitable bridges - look at the map and plan your route. What would you do in the lake district, or the Galloway forest - roads are where they are, not necessarily where we want them to be, we need to decide how we use them
