Lock No 13 ...

... at Whilton Locks on the Grand Union Canal.

Started near Daventry today - with another grey start I thought today was going to be a struggle to get anything to photograph but as it turned out I had quite a few to choose from.

I really liked this one - again for the depth of field but also for showing the lichen or moss (not a flora and fauna expert) on the opposite wall.

Hope you enjoy it !
