San Francisco

I've got back home today from my California trip. I've spent some time in San Francisco. It is a wonderful city, but driving there is so different from everything I've done so far.
First of all, it is very hilly, you have to use your breaks all the time... really all the time. And sometimes when you are driving up the hill you cannot see the road at all. you just see the top of the hill and it looks like there's nothing else... the end of the road, the end of the world. I was really scared seeing that. And although I've realized, that there is a road and this is not the end of the world - I could do nothing with my feelings.
Second, there are so many limits on turns within the downtown area. You cannot turn left at certain hours. That was confusing.
Third, some roads just disappear and then appear in some other place later. There was 101 road, which literally disappeared at one point and then appeared later on the other side of the city. And that was not our mistake or lack of attention, it literally disappeared according to the map too.
