Given it changed to dusk at the same few minutes I did, it is someplace along the eastern/central time zone. Some speculation was Greeneville TN based on planes spotted on cam and type of birds heard. I think it is a bit more west than that though say Louisville, Bowling Green, Nashville and so forth. It is 100% along that line +- 5 minutes sun. If it is near Bowling Green, I will become Spartacus for this thing.
It could very well be in a backyard or out in a county someplace, however I heard commercial backup beeps for about 20 minutes earlier on it. It is close to something besides a flagpole in the middle of BFE.
