Is the half-time scoreline important?

Seriously? This is Salthill, the place that trademarked the game of two halves where winning the coin toss is worth a few scores. With a forecast for rain and 30 km/h westerly winds, kicking into the Salthill-Knocknacarra club end should be a drudge on Sunday. Aside from the location, history shows it’s good to be up at the break. In eight of their last 10 SFC meetings, the team leading at the interval has ended up winning.
