  The strange quark hadrons sit at an important crossroads between the light
and heavy quark hadrons, but their spectrum is comparatively poorly known. The
KLF experiment was recently approved to run in Hall D of Jefferson Lab, and
will use an intense secondary beam of $K_L$ mesons with the existing GlueX
spectrometer to collect data several orders of magnitude larger than existing
dataset. In this talk, I will discuss the expected physics reach of this
experiment and the status of its preparations.
