Until Andrew Glover had the North Stand covered back in 2012ish the Southern end of the Western Terrace was generally seen as the noisy home fans domain especially when we were playing towards the hospitality boxes. Then we'd all troupe down to the North Terrace for the 2nd half (or vice versa if we played the other way 1st). Glover started a campaign to make that new North Stand the home end and following a kerfuffle with fans clashing during a Cas game began the segregation. With increased crowds this season we probably need to utilise the western terrace more when it's safe to do so.
Obviously all the old farts, as now, sat in the East Stand regardless of the above.
