Ok, you might need to dumb that down for me
I'm stumped. It's actually in g? Damn I was off.
So now that I get my handy dandy key chart, I see that D major is not located in the C major column. And I see that all those chords are located in the G major column. I don't really understand why but I now know to use my chart and that whichever chord ends the progression doesn't mean it's in the key of that chord. But the F major isn't in the G major column, so I'm still confused as to how the whole thing is in G major.
