I read it as these guys are surfing at night because it is crowded during the day.
And what is the main cause of crowding? I'll give you a hint...
...see your op.
Reminds me of Laird Hamilton bitching about the crowds at Peahi when the main reason it's crowded is because of his well publicized exploits there.
Here's my point, always was and always will be...
...you want to go surf? Go ahead. Just shut the fuck up about it, ok? And if you just can't control yourself and have to yap your trap in every way possible then don't complain about the crowds.
