Evening walk

Along an old railway embankment that runs behind the house is a lovely walk on an evening. It’s quiet yet we meet a few people and dogs, lots of greenery, squirrels and occasional fox.
There is one bridge still in place and someone has painted animals on it, they have been there for years my daughter tells me but I have never noticed them before.
We can hear people on the embankment when we are in our garden, but not see them because of all the trees and bushes.
