We study the topology of ``min-bias'' and hard collisions in Run 2 at the Tevatron by examining charged particle correlations. The \delta \phi dependence of the density of charged particles and the scalar pT sum density relative to the direction of the leading jet for ``leading jet'' and ``back-to-back'' events are studied. The ``jet structure'' in the ``underlying event'' and in ``min-bias'' collosions is studied by defining ``associated'' charged particle densities that measure the number of charged particles accompanying the maximum pT charged particle in the ``transverse'' region or the maximum pT particle in the event.
