LERF Unoccupancy Inspection
Walked down the RF gallery, test labs, GTS, GTS control room, LERF vault, and LERF control room. No off-nominal conditions were seen, smelled, heard, felt, or tasted. Extensive pictures of said nominal conditions are available, but will not be included on account of the sheer volume.
