And there was I planting cabbages and sowing carrots and radishes down on the allotment this weekend, when it seems I should really be trying my hand at something altogether more exotic. In amongst the cherry and plum trees, my next planting could well be an avocado if this article on the BBC news site is to be believed. I do have some tasty salad leaves to go with it, and maybe I could pull a nice big salmon out of the River Brent? OK, so that’s getting a bit too hopeful, but perhaps I could at least pull a shopping trolley out from the murky depths, and then I’d have something to put the packet in the next time I go to Sainsburys!
