Liam on a Leash

I took Liam for a walk tonight down to the shops to get hamburgers for dinner. I find that having a leash/harness thingo around him helps to keep him in line as he tends to walk all over the footpath as it is and threatens to go onto the road at times, another thing with him is that as he's becoming more independant he likes to walk on his own without holding your hand so this solves it, it allows him to have his own personal space to move-within reason!
He also is drawn for some reason to those the man holes and grates on the footpath-he has to walk over every single one of them!
...strange boy!
