I made my points in comments #7 & #8 at that post.
Do NOT go to the Federal site to leave your thoughts. You WILL be added to a list, and that list WILL be used to generate a visit from the FBATFE when these rules go into effect. Some of us are going to get those visits anyway, just because they can and just because they want to shut us up.
If you haven't bought all the military ammo and/or reloading components you will EVER need by now, you haven't been reading this blog, or worse, you've been reading it but let your better judgement take a pass. So, tell me, how's that new flat screen or that new kitchen remodel going to defend your sorry ass when the S.H.T.F?
If you don't have a Food Saver system yet, get one. You will need it.
Learn to navigate exactly to an off-road location without GPS (the old "pirate map" system). This will be important later. When the Feds impose bans, and folks have buried their vital drek, the first thing that will occur to the Feds is to degrade the accuracy of the GPS so that navigation to a precise location is no longer easy. I learned land navigation and orienteering before GPS, so I'm covered here, how about YOU?
