What the F?

I just found out the F train will be down and out in my part of Brooklyn again this weekend.  It was just down two weeks ago! And, once again, the subway will be down during the Brooklyn Book Fair.  The same thing happened last year and I complained to borough president Marty Markowitz.  (A lot of good THAT did.)  Yes, shuttle buses will be available, but it's still a pain.  Getting around when the subways aren't running is a huge problem.  Doesn't the MTA realize how much people depend on the subway around here?  Apparently not.
