I dont think its Class G though... because the only time you get clear of clouds is 1200 feet or less.
Correct me if im wrong, but from what I understand you don't need nor could you get an IFR clearance in class G airspace. Therefore you could fly as close to clouds or even in them in class G without breaking a reg. I would imagine you would at least need an instrument rating and an IFR equipped airplane. Not smart though.
