Here are a few things to keep in mind before you travel to San Francisco:

• Do not call the city San Fran or Frisco. It's San Francisco or SF.
• San Francisco is a weird city, from its attractions and events to its inhabitants. Keep an open mind while visiting.
• Pickpockets target high-traffic areas, particularly public transportation and Fisherman's Wharf. Don't leave valuables in the car, either.
• Don't rely solely on public transportation. Walking is one of the best ways to get around and see the city.
• You'll see locals wearing everything from hoodies and jeans to suits. Wear what makes you feel comfortable and don't be afraid to dress up a little when the mood strikes you.
• San Francisco can be chilly year-round. Pack a sweater or light jacket no matter what time of year you visit.
