You have nothing to do this weekend? I wish I could say the same, but its the 4th Annual NYABF and 2nd Annual CABC all under one roof at PS1.

A free opening preview is tonight from 6 to 8pm. And things really kick off tomorrow at 10:30 with the opening conference session. The Fair is entirely free and the bound-to-be intellectually stimulating Conference sessions are an affordable $20 each (or $100 for all 6 session and other assorted goodies).

In addition a slew of performances, talks and general fun have been arranged to concurrently happen in the Classroom at PS1.

Now what were your plans again?
