The building is still for lease, the fact they cannot even secure the lease should say it all. This is a typical no money down, hope and pray business plan, these business plans almost never actually come to fruition.
This is just a website and an idea. Lease would have to be secured then permits, approvals, reports and then financing before any construction could begin. That range is not even close to being a reality.
A real range project will not sell memberships or advertise until at least shovels are in the ground stage. Accurate membership prices could not be established until final stage, until then you would only be able to estimate a membership price.
