FAA can often be surprisingly helpful. It's not always their old motto of "The FAA is not happy, until you're not happy". You can't just fly your drone, even at 70ft AGL, legally, if you are within the specified airspace around an airport. Just because you are unable to contact anyone, does not give you the right to just go and fly, of course. Just talk it over with your local FAA office, they'll be happy and you'll be happy.
Thank you for the advice. I'll certainly take it into consideration. Your positive experience may be enough to offset all of my negative experiences with a large variety of government beauraucrats.
