I'm all for fighting this. When I moved to NH I was looking forward to being a little closer and going to their events, just to have them stop that same year. But to make this work there are things that have to happen. The first is that the club membership and leadership has to want it. They must know by now that there are a lot that will support them if they need it, and they do.
They need to open back up, at least the areas not in contention. The idea that a court can remove all means of income AND order a huge fine and payment is ridiculous and I can't see how that would stand if appealed high enough. If they can get this fixed, then they can raise money through donations and "membership", as in world wide. You're appealing to the millions of potential supporters who will buy a "membership" with no intention of ever going there, just to support the cause. Reach out to all the orgs GOAL, Comm2a, GOA, even the NRA not just for money but for promotion of the issue. Reach out to celebrities who are friendly to the cause for both money and promotion, and Trump, Barron and Don.
I look at their web page, that doesn't even load right, and you'd think it was business as normal. They tried to settle it, now it's time to fight. Make it well known that gov is being used to kill an American pastime, get the firearms community involved. Start taking donations! Set up a site to do this! Get Colion Noir and other YouTubers to promote this. Remember, if they get $1 from a million people their problems are over, it's all about numbers. Think about it Noir has 1.79M subscribers, if just 5% donated just $10 they could settle everything, or more likely get that $10 from a lot more people and have a war chest that would make the local town actually worry about.
This all requires that the club have the fight in them to do it, they could start by getting involved in the dialog here.
