Past studies of neutrinos and the recent results on neutrino mixing have opened up many new possibilities as well as the understanding that neutrino mixing is very different from the better known quark mixing. The last remaining unmeasured component of the neutrino mixing matrix (Ue3) also provides a window to understanding neutrino matter effects, the mass hierarchy, and the possibility of measuring leptonic CP violation. A discussion of the benefits and difficulties of pursuing such a measurement with reactor neutrinos will be presented. In addition, possible sites for such an experiment will be discussed, including a location in Brazil.
