chopper

I just had a chopper fly 3 circles above my house pretty low and then fly off, should I be worried? The same thing happened 2 months ago. Both times it was during the lights off period so they wouldn't of detected a heat sig. Any thoughts on this?

if you can honestly say to yourself that you are within your boundaries and means then i think that may answer your own question if you should be worried or not (given that you understand the law in your state)... if you are just worried about the choppers, then you should also worry about the traces that you left behind before the chopper incident.
