Yes, away fans are diehards who will nearly always have great unity. They meet the basic criteria of reaching that minimum engagement threshold everytime, simply by virtue of the fact that they'll all sing....
The corner position also means they sing across each other and up to expanses of barrel roof in both directions..... almost an amphitheatre effect. I was hoping our upper corner sections would have a similar effect for the South stand, and it has on occasion. Hopefully with time, that will come more often.
