I got my match ticket from 'ticketmaster' delivered to my front door - the official supporters had to mess around by collecting theirs' from a hotel in Dublin. I know which of these was the most convenient.
There was a definite under-current of disquiet from the locals against the Northern Irish supporters. It was OK as a Scotsman but sensibly the NI supporters headed back across the border at the end of the match.
It is very sad that this old enmity is still simmering along.
