Do first surfs exist? Probably not but I'm claiming it anyway. The flowerpots wave was spotted a few years back by AS Watersports when the river flooded and the second pots weir washed out. It only took about 6 months worth of rain within a week but this weekend i got to surf it. I also got interrogated by sky news who were reporting on the recent flooding and didn't approve http://news.sky.com/story/1016089/flood-scenes-shocking-says-david-cameron (not sure if link will stay up).
