You must have been getting bugged by that prick in the sanger at Folsom. Guy was going between me and the shore while my 10 year old daughter was in the water...we were probably 60 feet from shore... I think it was a DLX or barefoot model but the guy was complete douchery.
Sad part is he is just seriously unaware of the impact of his actions. Pretty sure he wasn't trying to be a moron. Some (most) people just don't know better and really don't care what impact they have on others.
My best advice is to stay away from folsom. Stay FAR FAR away!
