I really find it impossible to imagine. I have no contacts in SF: I did once email their press office to ask, but I got no reply. None of the published reasons seems to make any sense. Perhaps SF feels guilty about the economic damage inflicted on Clones by IRA activity in the early 1920s (see Terence Dooley The Plight of Monaghan Protestants, 1912–1926 Maynooth Studies in Irish Local History, Irish Academic Press, Dublin and Portland 2000). Or maybe it’s just that, of all the possible activities of cross-border bodies, this is the one most likely to provide photo opportunities and motherhood-and-apple-pie press coverage, showing the benefits of hands-across-the-borderism. But that seems too straightforward for SF. bjg
