I think you'll be surprised what the seventy years will do :) We have had an allotment site close near us and a few of the plot holders have come to our site, two of them have had their plots for fifty years The council did provide new sheds, greenhouses, their plots rotavated and manured. I said to one of them you must be gutted, he shrugged his shoulders and said it was just one of those things.
Well, they're the ones who have made the move - what about the ones you haven't met, who now stay in all day? From speaking to a few at the weekend, it sounds like thats what they see as their future.
