Radio observations of gas in the Milky Way and Local Group are vital forunderstanding how galaxies function as systems. The unique sensitivity ofArecibo's 305m dish, coupled with the 7-beam Arecibo L-Band Feed Array (ALFA),provides an unparalleled tool for investigating the full range of interstellarphenomena traced by the HI 21cm line. The GALFA (Galactic ALFA) HI Survey ismapping the entire Arecibo sky over a velocity range of -700 to +700 km/s with0.2 km/s velocity channels and an angular resolution of 3.4 arcminutes. Wepresent highlights from the TOGS (Turn on GALFA Survey) portion of GALFA-HI,which is covering thousands of square degrees in commensal drift scanobservations with the ALFALFA and AGES extragalactic ALFA surveys. This work issupported in part by the National Astronomy and Ionosphere Center, operated byCornell University under cooperative agreement with the National ScienceFoundation.
