I see increasing registration on the horizon with an increasingly longer and longer list of banned guns.
The worst involves confiscation. So if we're to plan for the worst, we have to deal with confiscation also.
Right now, are there local groups like you described? And are there enough for our side to win?
I would say yes on both counts. Probably not having back room meetings, but groups of like minded people who will band together if/when SHTF.
And yes I believe there are enough to win.
