Neil,
I work in city-centre Manchester and live in Chorlton, South Manchester - a twenty minute walk to OT. Getting a tram to and from the ground from the city-centre can be very very difficult, especially for an evening game. I have to leave work an hour earlier than usual to have any chance of getting home on match days. One option is to get the Eccles line tram and get off at one of the Salford Quays stations, therefore avoiding the busier Altrincham line.
