"Can I call you back? - I'm on the bike"

I'm riding across a football pitch and I notice my shadow.  I have my phone in my pocket and so stop to take a blip.  But once I've stopped I no longer see what I originally saw.  

So I have a go at taking a photo whilst riding  along.  Not the easiest thing to do - with a phone anyway.  Took about half a dozen attempts.
