The MiniBooNE experiment at Fermilab is designed to be a definitive test of the LSND evidence for neutrino oscillations. If the LSND evidence is
confirmed, then, together with the results from solar, reactor, and atmospheric neutrino oscillation experiments, it would imply Physics Beyond the Standard Model, such as sterile neutrinos, CPT/Lorentz violation, or mass-varying
neutrinos. After two and a half years of operation, MiniBooNE has collected about 500K neutrino events and is clearly observing charged-current quasi-elastic events, charged-current pion events, neutral-current pi0 events, and neutral-current elastic events. Some of these early, non-oscillation physics
results will be presented along with the prospects for the future.
