'Under the gov't radar' - you mean like paying or accepting cash for firearms, or trading firearms for firearms FTF from a like minded citizen of my own state who feels the same way I do about paper?Unless you planning completely removing yourself from the grid lotsa luck in remaining anonymous. From what little I know unless you are totally using only cash, don’t subscribe to any utilities, never file a tax return, don’t receive any public assistance, etc. there is no way you’ll stay under the government radar.
Unpossible, eh?
