I like the novelty wave or "invisibles" as we call it, you need to score it by chance that one time and try and suss out why it was good that day. You might ask a few crusty legends if they can predict it or just keep checking it over a period of time. You will get it wrong more often than not but after hours of fruitless checking you start to get some idea and be rewarded with uncrowded bliss, they may not be the best spots but that feeling of anticipation as you head there is priceless. Much better than just heading to guaranteed spot and finding 30 others have checked the camera or a simply too lazy to go anywhere else.
