Skorzik has been on the committee with ORBA (Ontario Road Builders Association) and he brings an abundance of enthusiasm and a wealth of knowledge to the IGGA. When he and his crew are not making highways a safer place, he can be found sailing on Lake Ontario, or overlanding the many natural trails in Ontario, Canada.
