conclusions: SDSS and DES have established a track record for FNAL leadership in building and conducting cosmic surveys (science and technical). We have experience in building data processing, database, and archive systems; building a working multi-institutional scientific collaboration; and building a focal plane. We have developed internal scientific expertise in key areas related to cosmology, and can help catalyze broader participation to advance the field. Connecting surveys is natural, e.g. DES + VISTA + SPT + SkyMapper. All of this means we are well placed for the next survey!
