We study the static potential using gauge configurations that include the effects of two flavors of dynamical Kogut-Susskind quarks. The configurations, generated by the MILC collaboration, and used to study the spectrum and heavy-light decay constants, cover a range 5.3≤6/g2≤5.6. There are at least four quark masses for each coupling studied. Determination of r0 from the potential can be used to set a scale. This alternative scale is useful to study systematic errors on the spectrum and decay constants.
