I showed up there as a single and got right on. In fact, they gave me the option of playing as a single or joining a twosome. I took one look at the opening hole, had no idea what was going on, and figured I’d be better off playing with some people who knew the course. However, that was back in 2018, and with the explosion of interest in golf during the pandemic, maybe you can’t do that anymore? Hard to believe every group is a four ball, and I’ve always found that the majority of groups with openings are more than happy to have a stranger join them. I just spent three weeks in Ireland as a single doing exactly that.
