Exit route?

I'd promised fellow Scot Alison, now translated to Kansas, clouds for today. But I couldn't resist this topical photo on the day when the UK government took a majority stake in RBS - the Royal Bank of Scotland - in response to our own little corner of the global financial crisis.
And what's their emergency exit route?
There seems to be an opening at the other end. A glimmer of light beyond the thick vegetation. I certainly hope so for the sake of the RBS staff.
