Thanks to those who've posted here & elsewhere, I now know how & when to get to Skerries, have a map of the town, an idea of where the racing takes place, and a map. of sorts, of the course.
I've also found websites for the local tourist office and for the club that runs the racing.
What I still need to know is what time the racing takes place (even approx., i.e. is it all day, all afternoon, evening only?), a map showing the route from town to the races (I've sort of worked it out, but I'd like to know from which side I approach the racing), and are all parts of the course generally accessible, i.e. can I walk round to various vantage points, go & have a nosey around the paddock, etc.?
Any info & advice welcome. IoM TT veteran, but new to the Irish races.
