Shropshire Union Canal
Norbury is a strange sort of place. Mention it to any canal enthusiast and they will know exactly where you mean, a bit like knowing the whereabouts of Peterborough to anyone else. But mention Norbury to a non canal person and all you will get are blank stares.
It's a case of quality triumphing over quantity in my opinion, and well worth a stop at the visitor moorings if you have the time.
