Burying your guns won't do you any good...ya can't use them if they are buried.
Founding fathers never buried theirs. Just a thought.
If someday you looked down the road a 100 yards or so and saw a small group of people trying to collect your neighbors guns....you would be better off taking a couple of them out looking through your scope, than having your guns buried. Confiscation would STOP for that day in that neighborhood. They know this would happen in many places. They are not stupid...and you would not find hardly anyone to take the job of gun confiscation. The police in this area would not do this...that's for sure.
I doubt it would ever come to this...they know there are many places in many States where guns will never be confiscated, they know this for a fact. They will find other ways to do this slowly over time, make it hard to get ammo, drive away gun manufacturers, lot of things they can do over time.
But no matter what happens...I won't hide my guns...might be different if I had small kids to raise up, but they are all grown...so it's just me now.
