Soooo.... If you are over 3000ft you don't have to have sight of the ground?
Correct. You only have to maintin the requirements for VFR flight, ie. VMC, as stated above.
In fact. you don't below 3000' either, so long as you maintain the more stringent 'Below FL100' requiremenmts for VFR.

Ps. Foxmoth, as always, inserts a valuable note of pragmatism into the legal debate. Just because it's legal, doesnt necessarilly mean its the smartest thing to do!
