Living in London, as I do, one tends to think of the Thames as nothing more than a dividing line between the lovely North and the grotty South. Unfair on many levels, but mainly because, having just spent a weekend in the Berkshire village of Hurley - midway between Henley and Marlow as the river flows - I now know it to be a divine stretch of waterway teeming with life and beauty.
And what's more, if, like me, you were under the aforementioned illusion, it can be shattered moments after arriving in this delicious slice of England's green and pleasant land.
