Exploring the Nucleon Spin the Next Decade

I review aspects of the physics case for a polarized electronproton collider including present plans and layout of the collider at BNL. Investigations of spin with such a collider in the next decade will be a logical extension of the RHIC spin physics now being pursued at BNL. In describing the physics case, I will highlight the topics that were of particular interest to Vernon W. Hughes in whose memory this article is written.
