Another Sunday afternoon wandering about on, under, and around the arches at Hockley Viaduct. The spring sunshine came and went, and rain threatened but never fell. Most of the time I was whistling (attempting to whistle) the Aria of the Goldberg Variations, or singing (attempting to sing) the theme from the Sharpe TV series, "Over the Hills and Far Away". I have no idea why. It's what I do when I'm out on my own, trying to get "in the zone".
