Challenge accepted

On our dog walk yesterday we came across this log which I obviously wanted to walk along but failed miserably. It was very wobbly.
Mary thought this was hilarious due to all the fuss I made about nearly falling into the several inches of stream coursing underneath and duly challenged me to "do it properly" next time we past it.
So being a bear man of very little brain I risked life and limb to accept the challenge. This is me just about to complete said challenge.
Job done.
