Well actually in Whitstable Lutonman! Mrs Stewie and me had walked from Faversham railway station to Whitstable via the Saxon Shore Way and after a cop of tea in the castle gardens, was making our way to the station via a lovely footpath leading from 'Stream Walk'. The footpath is decorated along its length by artistic murals of which the picture on the bridge forms part.
The bridge itself is (just) visible on GSV (see attached), and was also featured in an article in Kent Online, concerning Network Rail cleaning their structures of graffiti (see attached), though I don't believe that they meant this one. Back to you then Lutonman.
