Wherever you sit mate, there's going to be a LOT of Fijians. I didn't know this but outside of London, the town of Rochdale hosts the most Fijians in the UK apart from London. With Rochdale being only thirty minutes drive or so away from St Helens, I expect they'll make the trip in their numbers and then some. I'm in the north stand, which is where I sit every week with St Helens.
If you need a hand getting around the town or the stadium and so on, please don't hesitate to send me a message on here, I'll give you all the directions you want.
