Newry City have recently added a new stand(riddiculous for a club with an average attendance of 150) and as you say lots of grounds in the Irish leauge have upgraded of late.
From what i know there is/was a lot more funding available in NI and a lot of it through the peace funding programmes.Im told though that Newry City FC have a rich benefactor,much the same as SP Franchise so expect both to go belly up soon
