Concerning San Francisco: You do your best to ignore certain features and I don't take my kids there.

You've just given me an idea.

Movies, TV shows have ratings such as G, PG-13, R, X, etc. Why not do the same for cities, districts, etc.?

It's for the children.

Actually, if you made it district specific you have an IDEA!
Kids - you can go to the Marina, but not to the Castro, etc.
