Myself and another photographer are going, there are actually two board members going that I know of, they will have family members in tow, I know two guys from Cork that are regulars and I know a few guys from Dublin that will probably attend RIAT in one form or other (show days or park and view).
Irish guys can turn up anywhere, I met a group at Beauvechain in Belgium last year and met a few others at the back gate of Fairford during an exercise, not RIAT, last year!

Frank.
