Beach wedding reception in california?

OK, everyone's really being helpful with the answering of which beach to be married at along the california coastline. NOW, here's where I've been having trouble finding information. I want to set up a canopy, and have the reception there, on the beach, not at a restraunt nearby or at a hotel, right there on the beach. Now:). Has anyone done this yet or know how it can be done, if it's ever been done? I'm planning a sunset wedding, with the reception afterwards, but a brunch before the wedding, complicated right?:) but... the tent will basically be up all day, so. Anyone knows how and where I can accomplish this? thanks
