In 2005 the Galactic Legacy Mid-Plane Survey Extraordinaire (GLIMPSE) found the Milky Way to contain a long bar within its structure, the results of this survey were unclear though of the full size, structure, and dynamics of the bar. Studying the bar is difficult due to the large extinction in
the inner mid-plane of the Galaxy. Using the Two Micron All Sky Survey (2MASS) and GLIMPSE I & II a large number of evolved stars, bright in the infrared can be identified in the area of the long bar. To explore the kinematics of the long bar, spectra of candidate long bar stars have been obtained to measure radial velocities, to measure the extent and kinematics of the long bar. Here we present
results from our first set of stars at |b| 3 deg.
