San Francisco...where do I begin? We are on the coast of the US, right on the Pacific Ocean (which is freezing!). We have two beautiful bridges leading into the city -- The Golden Gate Bridge and the Bay Bridge. I have to cross the Bay Bridge everyday to get into the city, pay $3, and it takes FOREVER! Traffic in our town is horrible. Sometimes I will take the train into the city, known as BART (Bay Area Rapid Transit), which travels beneath the water, and for this I have to pay $4.85 each way...but I get tons of reading done this way.
San Francisco is a place that embraces diversity and culture like no place I have ever been. If I take public transport in the city, I can find myself surrounded by 15 different ethnic groups or more, or people who embrace all aspects of their sexuality, and everyone walks around like all of this is normal. I love it! The people I work with may have 20 different piercings, tattoos on every part of their body, and be embraced as genuises by those around them without judgment. Just to give you an idea of the diversity here -- my immediate colleagues are from the Philippines, Vietnam, Chile, China and Japan.
As for the weather in San Francisco, it's very strange. The fog settles right into the city, especially during the summer, so our summers feel like winter. The best time to visit SF is in September...beautiful weather! I live across the bridge where the temperature can reach upwards of 100 degrees, but I have to dress for 60 degree weather before I head off to work. You can walk one city block and have a 20 degree difference just within the city itself.
If you want to visit SF, you will have plenty to see and do -- check out places like Chinatown, Fisherman's Wharf, Golden Gate Park, North Beach, Napa Valley. And we are close to natural wonders such as Yosemite, Muir Woods, King's Canyon, Lake Tahoe, Big Sur...oh, too much to name!
