  Quark-Gluon plasmas produced in relativistic heavy-ion collisions quickly
expand and cool, entering a phase consisting of multiple interacting hadronic
resonances just below the QCD deconfinement temperature. The transport
properties of this hot hadron gas are poorly understood, yet they play an
important role in our ability to infer transport properties of the quark-gluon
plasma, because experimental measurements integrate over the whole system
evolution. Assuming that the hot hadron gas can be modeled by a hadron cascade
code based on kinetic theory assuming binary interactions, the shear viscosity
over entropy ratio of a hot hadron gas for temperatures in between 120 MeV and
170 MeV is extracted. Furthermore, we present estimates for a second order
transport coefficient, the shear viscous relaxation time at a temperature of
165 MeV.
