plus we are more feral than those croweatersI think the major difference to the big Vic teams is that the crowd is so one sided in Perth, I don't know the figures but for most games I can't imagine the number of away fans numbers more than 2500 max.
Once 55,000 or more fans start making noise in unison that is pretty intimidating. For that reason I would suggest that Adelaide Oval is a similar challenge for away teams. But I reckon the noise factor combined with the extra travel would make Perth the hardest place to play as an away team.
