London's abandoned rail and tube lines have been put to many novel uses down the years functioning as bomb shelters, impromptu party venues and film sets for Hollywood movies.
But a new idea to create a mushroom garden in a tunnel beneath Oxford Street is perhaps one of the more unconventional attempts to breathe new life into the UK capital's forgotten subterranean murk.

For Logan Cox, there is food all around you.

What do you do with a 12-year-old niece who has just started her summer vacation and is already bored? You put her to work picking blueberries.
I picked Susie up early so we would beat the heat. My pick-your-own fruit history was limited to apples and peaches, so I wasn’t sure how labor intensive, bending, stooping or squatting, the picking would be. It turns out to require a bit of all three, but not to a point where my back hurt.
We arrived at Homestead Farms in Poolesville, MD just before 10 a.m. loaded with re-usable plastic blueberry containers and sturdy bags. After a quick tutorial on how to identify and pick ripe berries we were off. A ripe blueberry is entirely blue. If the berry has a hint of red on it then it will still be a bit tart.

As soon as we posted the menu for last night's White House State Dinner, the question began rolling in from my colleagues, commenters, folks on Twitter - and I realized I oughta get my head out of my ramp patch and explain.
