Cleaning up...

Cleaning up the grass between the stones. Yesterday I did the same with my high pressure washer. Thought it was good enough. Have done it some times. Seen the grass coming back too. Today we got the information from our son that the grass will pop up again if we are not pouring boiling water between the stones. I was boiling the water in three pots running to and fro filling up Mrs B`s watering can. Packing tonight. Going to the summer house tomorrow where we will meet  Josefine and her parents.  See if the grass between the stones have come back next time in Oslo.
