I will then talk about the reconstruction technique used in the BOSS survey and present some of the cosmological measurements made from the final data set. Finally I will talk about the upcoming DESI survey and describe preliminary work on techniques we hope to use to ensure our BAO measurements are not biased by the instrument.
