  The eventual prospect of muon colliders reaching several TeV encourages us to
consider the experimental opportunities presented by very copious stores of
muons, approaching $10^{21}$ per year. I summarize and comment upon some
highlights of the Fermilab Workshop on Physics at the First Muon Collider and
at the Front End of a Muon Collider. Topics include various varieties of
$\mu\mu$ colliders, $\mu p$ colliders, and applications of the intense neutrino
beams that can be generated in muon storage rings.
