We analyze our CO line data (Wilson et al. 1999 ApJ 525, 356), lower resolution data of Castets et al.~(1990 A & A 234, 469) which covers a larger region, and unpublished results. The goal is to test whether the Photon Dominated Region models of Stoerzer et al.~(2000 A & A 358, 682) are a better match to the CO and CS data for sources over the entire 2.5\rm o long Orion Streamer. We compare conditions in the individual Orion Streamer sources to prominent sources such as Orion KL, and propose a global model of the Orion Streamer.
