surfing in thick fog

Well i thought i would wake up early and go for a 7am surf to beat the weekend crowds the only snag was it was foggy very foggy. It wasnt particually crowded but there were enough people to make it pretty dodgy. Every time someone caught a wave i would hear a loud yell saying "im going right" or "im on a wave" the visability was poor but you could still make out the shapes and such.
Anybody surfed in conditios simular or worse? I'll say one thing it kept me on my toes the whole time
