Have been thinking "I'm sure I've never been able to see the river under that bridge", but I'm afraid when half awake and vaguely in a hurry, and keeping half an eye out for kingfishers, I didn't stop to inspect or think very much about it. Bit worrying being that unobservant really, since I cycle that way every day. Heather
