In the same way that you can't really call The Hitchhikers Guide to the Galaxy a trilogy any more, Google's once again stretching the definition of a street. The company has loaned out one of its backpack-worn trekker units to the UK's Canal and River trust, which will document 100 miles of the country's waterways for Street View. Users will be able to tour London's Regent's Canal, the Bingley Five Rise and the Stoke Brueme blacksmiths on the Grand Union Canal. Just remember folks, even if you're touring from the comfort of your laptop, it's not a proper rambling holiday unless you bring a packed lunch and a flask of weak lemon drink.
