Thank you all very much for your replies, wishes and thoughts. It's super to know that all has not been in vain. Upon reflection - now that I'm no longer active in my garden - I'd say that that piece of field which we (about 140 of us) turned into a whole patchwork of allotments in the early nineteen-seventies has played a decisive role in my life.
I once remember how we, as a young, freshly married couple, visited another couple in London who showed us their garden. The fact that there, in the middle of such a city was a garden with vegetables in it seemed impossible to me at that time.
How things change.
Once again thanks for the invitation to continue to occassionally write on this site, I'll do that.
