21 billion midges
According to this article, 21 billion edges were predicted for Scotland’s 2017 midge season. I reckon that a fair number of them, like me, opted for a trip to Ireland that summer, boosting the already thriving local population.
Those pesky creatures turned these peaceful spots into pure torture, at dawn and dusk respectively.
On my Not To Do list: do not venture here again without a midge net and repellent.
