your edit is correct...San Fran is in Northern California. My only advice is to bring lots of layers of clothing! If you have a kayak, make sure you have a wet suit....frigid water. I went to college about 30 minutes from the water, but that's the reason nobody went to the beach. Supposed to be a lot of sharks, too. I would think the more fun trips are the Southern California ones, where you can tie the trip in with Disney, the San Diego Zoo, or Seaworld. I was sort of amazed in college how different the two areas were. There really should be three states in present day California. You have Northern California, the Central Valley (who says happy cows come from California????), and Southern California. Beyond that, they play separate state tournaments in high school sports--north and south. The best ballparks are in San Fran and San Diego, although Oakland's was always a pleasant place to watch a game. The minority populations are different (hispanic in south, asian in north). Weather is also very different. I think I remember shocking people that San Jose's latitude was similar to Cincinnati's. Most people in the midwest just assume all the weather is like San Diego. Remember how Packers fans in the 90s resented the Cowboys? That's how 49ers fans view the Packers. And don't go around saying you're from Wisconsin, since few in California could find it on a map. They pretty much ignore the existence of most of the US between Las Vegas and the eastern seaboard. I went to college in CA for 4 years and now live in a feuding border state--Arizona. Don't talk politics there. In the midwest, people have all sorts of beliefs but tend to share common values (they just have different perceptions). In California, they're very open, warm and loving, tolerant, and peaceful......unless they find out someone doesn't share their exact views. (mods, feel free to delete that part. Just wanted to warn the author since most midwesterners have views that can get dirty looks in CA).
