That statement is highly hypothetical.
There is NO documentable truth to any of it. Yes, many will spend $10k+ on their rigs. But since there are NO private parks here, there is no proof that ANY of us are bitching, whining, or no showing up to support a private park.
I pay $$ every time I go to Evans (for the Forrest Pass), as do most of us. It is my belief that most everyone would pay either a daily fee, or a season fee, to support a private park.
However it is also my belief that the financial support a private park would recieve from the general public is directly proportional to the terrain, variety, difficulty of the trails. The more trials, the more varied the trails, and the more difficult the trails will greatly increase traffic and revenue. The less trails, the less varied the trails, and the easier the trails will greatly diminish the general public and decrease revenue.
Of course and as always, these are simply MY opinion, and y'all are entitled to think something completely different.
