We prove that Garsia and Remmel's q-hit polynomials for Ferrers boards have
only real roots for fixed q > 0. This generalizes previous results by Haglund, Wagner
and Ono  and Savage and Visontai . We also extend the main recursion in 
to hit polynomials for certain classes of Ferrers boards, which include the multiset
