Photobomb!

There I was taking a quick photo of Euan who was engrossed in my I-pad when Isla just popped up as if to say "Oi, me too!"
We were looking after Euan & Eve and Euan had got a bit fed up with pushing trains round his track so I showed him some train videos and he got really into that.
He is train daft - wonder where he got that ?!
