Here is a piece of the Oldton map that has a lot of empty space in it. You could fill it with a specific memory or farewell.
What I do know about this sector, based on my first ever Oldton photo (and from a subsequent picture of the same spot taken at a different time of year) is that the houses here are Georgian, and there's car parking space on the road in front of the houses.
My father must have parked his car here fairly regularly. Did you ever live in a Georgian house? Did you notice a red car parked outside your window? Did the man who drove the car look like a nice man, a friendly man? Or was he sad-faced, slow-moving, remote... as if he had something on his mind?
