  To make progress in learning the underlying fundamental theory, it will be
necessary to combine bottom-up phenomenology and top-down analysis -- in
particular, top-down is unlikely to succeed alone. Here I elaborate on the role
of both, and describe obstacles that need to be overcome to help data point
toward the underlying theory, as well as approaches that might help to bypass
full systematic treatments. I also summarize arguments that superpartners are
probably being produced at the Tevatron Collider.
