We got off LIGHTLY.

After seeing some of the mayhem wrought by yesterday's draughty conditions, we escaped virtually unscathed.
The door had, somehow, been opened. I'm not 100% sure, but there's a fair chance this is the route Willy Wind took to start his little bit of mischief. The nearest pane was taken out and moved 2-3' "towards" the camera, the only other visible, vertical, pane was taken from its mounting and waved around a wee bit before I used a few rake handles and piles of bricks to keep the two of them, more or less, in situ overnight.
And, just for fun, it decided NOT to taunt us with any rain in addition to the wind.
As I said: we got off LIGHTLY.
