I've played in this the past two years and the four person Scramble format makes it huge amounts of fun. The team I was in last year won the event with a ridiculous score of 13 under, but it was never less than a blast playing with a group of friends for a good cause.
The event is run by Darren Murray who volunteers for Mellon Educate and all funds raised go towards the charity. A team of 4 costs €120. The details, with some additional images, are below.
It's a great day out, there are plenty of prizes and you're helping a good cause. What more could you ask for!
