Long-duration GRB (LGRB) 020819B was an exceptional object. Most bursts are bright and their hosts are faint irregulars. GRB 028919B was a dark burst located in a blue structure on the extreme edge of a spiral galaxy. There is strong evidence that LGRB hosts are typically faint because they prefer low-metallicity environments. The lack of optical emission from 020819B may suggest significant foreground extinction, however. We propose to obtain high signal to noise spectroscopy to determine the metallicity and relative velocity of the host and the blue outlying region within which it is localized. This will allow us to determine if the host region is part of the disk or a satellite, and will allow a local metallicity measurement. Nearly all metallicity measurements of GRB hosts have been global. None has yet been done on a dark burst.
