So my sister was in LA visiting me for 2 weeks. We went down to San Diego & visited San Francisco/Oakland.
We went up there with megabus.com. I definitely recommend this if you have a limited budget. If you book a couple of weeks in advance you can get one ways for 1$

I'll post a page with more pictures later, but here's 2 for now.
On the left is obviously the Golden Gate Bridge which was a bit tricky to get to by bus haha but we got there at the right time cause right when we left there was so much fog that we couldn't see a feet in front of us. The one on the right was taken at the Rose Garden in Oakland
