Two CO surveys are analyzed with the standard CO conversion factor. The main results are: (1) For each survey the cloud virial parameter $\\alpha_{vir}$ increases by a factor ~2 from galactocentric radius $R_{gal}$ = 4 kpc to 15 kpc. (2) PVE models match these trends only if the surface densities of survey clouds and nearby stars are comparable.
