The Caged Bowler

I was walking along our street opposite the bowling club when I spotted this lone bowler practicing from end to end of the green. Not another soul  to be seen and he was totally focussed - or totally depressed with his form.  I took this to practice my f8 challenge, but have now found I have nothing else.  Only Mr. Hobbs could approve of the cyclone wire, but it is all I have to offer.
