FWIW, here is my friend Will Shetterly's advice on starting a new narrative, when the starting does not come easily:
What I would tell someone in my situation to do is to think about an interesting incident that would occur as the point of view character is approaching or first at the new location. Doesn't have to be a big incident, and don't fall into doing something just because you think it's interesting that will then require a distracting flashback to explain what's going on. Remember that the situation is inherently interesting. The POV character is arriving at someplace new. What does the character hope for? What does the character fear? If you've got that, you're ready to write.
