We have literally got a stream running down the side of our lane at the moment
Funny you should mention that! I was thinking of digging a ditch in between my lawn and the patio as that area was constantly flooded after rain and became a clay play pan. I might actually do it as it would take the rain water to the other side of the lawn.
If it's too wet, better let your hub have a rest. Nobody wants to take a tumble in the clay-y piste!
