After verifying that the 2 local airports would be "ok" with me "flying nearby" (well, they are private grass strips that the FAA still calls airports, and they were covered in a foot of snow -- used by crop dusters in the summer, attached to two dairy farms, and at this time of year they were more than abandoned), I flew my drone near Holy Hill in Erin Wisconsin. I decided to stay well off the Holy Hill property and air-space, out of respect that people might have been worshipping there at the time.
