We present preliminary results from our chemo-dynamical survey of two Milky Way dwarf spheroidal (dSph) galaxies, Draco and Ursa Minor. The two galaxies have similar radial velocities and reside in close proximity in the outskirts of the Milky Way halo, yet exhibit noteworthy differences in their morphologies. We obtained spectroscopic data with AF2-WYFFOS on the WHT for several hundred red-giant-branch (RGB) candidates in each galaxy out to its tidal radius, from which we have identified approximately 100 velocity members in each system. Metallicities are determined for the individual RGB stars using the C
