Oxfordshire evening

Looking across the Oxfordshire way to the first (or last - depends on where you're starting from!) folds of the Cotswold hills. This is the so familiar view that you see if you walk up the road from my house. The mist, following a gloriously sunny day deliniates the tree line beautifully.
So, why did we spend most of the day at the "French Property" show at the National Motorcycle museum? At times like this it's difficult to see why we would want to leave such a lovely place.
