Not as easy as it looks!

Bryony kept Grumps company on one of his trips out around the circuit. On the way back she hitched a ride on his lap having pushed him some of the way.....it was just the 2 of them out together. She then wanted a go in the chair herself but even getting out of our lane proved impossible as the chair has a mind of its own and she kept ending up in the ditch! "Hmm, how does Grumps do it...it's not as easy as it looks!?"
