Nick considers himself a rider. He’s ridden horses, and sometimes he’s guided people, too. When others have ridden with him, he’s always taken special care of them, because he knows horses can be difficult. He hasn’t ridden only horses. He’s ridden anything he could.
His friends have ridden camels on their farm - it was a special farm and they were quite rich. He’s ridden camels when he went to visit. But riding horses was his specialty. Nick considers himself to be an expert rider.
