In most, if not all sports, referees have a hard role, as there will always be someone to complain about a specific call, but overall, most do their best to call a fair and even game and remain respected by players, coaches and fans.
One NHL referee that garners plenty of respect is Dan O'Rourke, who has refereed over 1,000 games in the NHL, and is now taking a big journey for a fantastic cause.
He is now cycling over 2,700 miles from Santa Monica all the way to Chicago, and now he's almost half way through the gruelling trip.
The reason for this trip? Honouring his father who dealt with vision issues his entire life, but inspired those around him by never letting it get to him, and now O'Rourke is doing this trip for the National Federation of the Blind.
