A Staged Muon-Based Neutrino and Collider Physics Program
  We sketch a staged plan for a series of muon-based facilities that can do compelling physics at each stage. Such a plan is unique in its ability to span both the Intensity and Energy Frontiers as defined by the P5 sub-panel of the US High Energy Physics Advisory Committee. This unique physics reach places a muon-based facility in an unequaled position to address critical questions about the nature of the Universe.
