San Francisco Bay is at the top of the startup scene. There is nowhere else were you will find the number of investors or resources (meetups, groups, talent, funding circuits, etc.)

I'm from Chicago and while the startup scene there is pretty solid (cheap rent, large city, big financial center for funding) SF Bay is in a league of its own (maybe NYC also).

That doesn't mean you won't find investors, resources, etc in other cities. Is basically the same as asking whether you should go to a top 10 school or go to a top 50 school. You can have the same amount of success at both opportunities its just how much effort you put into it.

Moving to silicon valley won't make your business successful, but it will give you access to the tools and connections you need to help yourself. These same tools exist elsewhere but you might have to search a bit harder.
