Be afraid, be very afraid.
I'm from Wexford, went to college in Waterford. Last count there were, hang on, um, err, exactly NO GOOD TECHNO NIGHTS WHATSOEVER. Sorry.
I'll email my mates still living there and report back to you soon(ish). When are you going by the way ? I'm hopping over to Wexford sometime this month. Not sure when yet.
