I did the same as you Grob a while back. I was getting squeezed down by the cloud until I was at 900', with terrain up to 300' below me, with hills to 900' around me with antennas up to 1300', hidden somewhere ahead of me. I tell you it was a scary place to be. The difference between your flight and my flight was when I had had enough, I gave it full power and climbed to FL45 and became IFR.
I was doing this VFR flight as an experiment to see how far I could go, and to be honest had I not had instrument training, I would have probably ended up in a field....I recommend getting an IMC it may save your life sometime....
Under IFR, you have to be at least 1000' above the nearest object within 5nm
Unless intending to land of course.....
