During the Second World War, with food-carrying ships from the dominions being sunk in large numbers by German U-boats amid fears they might starve the UK into submission, people all over the country - Brigg included - were urged to Dig for Victory by growing fruit and veg on waste ground, parks and golf courses.
We were reminded of this - 70+ years later - by an email from Brigg Blog follower Jackie Brock, the former town councillor.
She kindly alerted us to a tomato plant growing on a traffic island in the middle of the A18, near the entrance to our Tesco store.
We went to take a look and here are the pictures to prove the existence of this wonder of nature.
With thousands of vehicles passing within inches of its precarious perch, the perky plant has prolonged life long enough to produce fruit.
Back in the late 1960s, a practical lesson at Brigg Grammar School saw us sent out to the A18 to meaure dust particles which formed a film on plants growing near the main road, including privet leaves. We discovered an awful lot of pollution.
Back then it was all leaded petrol, of course. So perhaps the survival of our tenacious tomato is linked to the switch to unleaded fuel.
Going back even further into the 1960s, while at Glebe Road Primary we used to grow mustard and cress by putting seeds on soaked blotting paper. It was amazing how the plants grew without soil.
