Location, race, and game in North America. Should some regions/places be avoided by guys if they happen to be a particular race?

I have noticed that based on race alone, some guys can have dramatically good results in one area but do poorly in others. A main example I have noticed is that some cities like Toronto and San Francisco are awful for Asian and Indian men regardless of what their SMV is. Women of their races have a strict preference for white guys and despite the liberal reputation of those places, white women there are not quite as open to dating interracial (if they are it is only with black guys). Some of the black guys I talk to have said that they find it very easy to get high quality girls in places like Minneapolis and Milwauke where a lot of the girls are only raised around whites but happen to have a major curiosity for black men.

California seems to be heaven for black guys who want to go interracial but hell for asian and indian men.

What I am asking is this, should some regions of the USA be avoided by guys of certain races regardless of what their SMV might be? I seem to get the impression that Toronto and San Francisco are practically hell for Asian and Indian men because on one hand, white women there would rather go lesbian than date one and on the other hand women of their own race tend to go interracial at higher rates in those areas.
