The best thing fans can do to help on away trips is travel and support the team. The players and Andrew Lord have said what a difference it makes, so they've already told us what to do!
A lot of people have commented on how we won there in the Challenge Cup Final, the biggest difference in that game was that there were 8 coach loads and many more fans cheering the team on. The best performance since was the league decider when again there were many away fans.
I'm in no way suggesting this is the main reason for the different results, but given what the team have said and the results, surely the only thing we can do is get on the road and support the team as much as possible?
