I play most of my rounds as a single, or end up joining a group through my round. I find the worst part of being a single is being able to get on. Recently, with all of the Covid-related changes, the courses near me would not allow walk-ons. The problem was, their website didn't allow you to book as a single. I enjoy playing by myself, but have also met many really cool people along the way. One suggestion I have, especially if you play the same course alot, is to exchange numbers with guys you enjoy your round with. This will allow you all to check-in with each other about the potential of playing together again. I've never had a horrible experience as a single, there were a couple times there were people I was paired with, that I hope I never meet again, but that's it. Good luck moving forward!
