Well, approx 50% of the state belongs to the National Park service. We also have 2 major military bases there-San Diego and Fairfield (Travis). Those would have to be relocated. Cali should pay fair market for the parks as well. Cali would be broke for centuries just paying for those.
Oh, and in other news, Nestle corp just announced they are moving to Alexandria VA out of Glendale CA. Keep on running businesses out of the state ya idiots !!
