So stop calling yourselves a club, stop paying a cent for the lease, and just walk in and use it anyway.
IMHO, the people own the land, not the Forest Service. It is not the role of the Forest service, or the Federal Government for that matter, to be using public property for financial gain.
Then go out and find a timber company that will give your club a hunting lease for a lot less. You can shoot there, and hunt there too.
Or get a loan a buy land. Yous should be able to get at least 30 acres in Colorado for $20,000, and then you own it. You don't have to pay another 20 Grand next year.
That is, until the Democrats take power again in both the Congress and the Presidency. Then they will use Eminant Domain to throw you off your land and will use gun control laws to take your guns.
