Opportunistic

Imagine my dilemma:

On my way home from the DIY shop and I got stopped at the level crossing.
With my camera in the boot.
Could I retrieve it, fiddle with the settings and get ready for a one-take shot before the train came?

How did I do??

I did get some funny looks from the two occupants of the panda car on the other side of the barriers.
But that's what blipping is all about right?
