After a general introduction and program news survey, some areas of recent physics progress are considered: the matching to matrix elements, especially for W/Z production; charm and bottom hadronization; multiple interactions; and interconnection effects. The report concludes with some words on the future, specifically the ongoing transition to C++.1+8 pages, no figures, to appear in the Proceedings of the QCD and Weak Boson Physics workshop in preparation for Run II at the Fermilab TevatronHigh Energy Physics - Phenomenologytext
