Clackmannan Bridge

Taken from just north of Airth (as in where on .... are we?!)
This new bridge cuts a long swooping line across the Firth and, from this angle, obscures the old Kincardine bridge. If you look closely, you may just make out the old bridge. MaggieD concentrated on the blinding yellow fields and the sky so I looked over to the river for inspiration. Rona just kept pulling on her lead!
It was good to get out after the heavy rain this morning but we did get some much-needed indoor stuff done. We were lucky earlier; took Rona for her early morning run round the wood and managed to get back home just as the rain started - perfect timing.
Now, a little question:- On the north shore of the Forth, between these two bridges, is a radar dish thing. As it is rotating, it is obviously working, but why? Anyone out there in Blipland have any ideas.
