if you’re serious, get a post hole digger, bury them vertically and least 2’ below ground and place it near an area that has lots of metal already. Fence line, junkyard, that sort of thingOther than being watched more closely I don't know.
They might be making lists of people who've posted pics of guns that they don't think you should have. But that info is probably available elsewhere and lists already created.
I'm just trying to decide the best place to bury my stuff (if I had any) so the dogs and metal detectors can't find it.
