The distribution of Milky Way Dwarf Galaxies has been suggested to contain anisotropic subsets of 'ghostly streams' and groups or even to be distributed in a flattened 'Disk of Satellites'. Recent surveys have facilitated the discovery of larger numbers of satellites and we investigated their distribution using a suite of clustering estimators. We also applied the same analysis to the Via Lactea II dark matter simulation and several subsamples selected following recent suggestions. We consider both all dwarf galaxies within 260 kpc and a subset of only those found within the northern contiguous portion of the SDSS DR7 Legacy Footprint. We will present our results and discuss their interpretation.
