We discuss possible studies of parton distributions at the proposed 50-GeV PS facility. First, comments are given in general on the importance of large-x physics for finding new physics. Second, polarized deuteron reactions are discussed in connection with new structure functions which are specific for a spin-1 hadron. Third, if the polarized proton-deuteron Drell-Yan process is studied at the facility, it could provide information on the light-antiquark flavor asymmetry in the polarized distributions.
