Do NOT assume that "Unlimited Miles" means unlimited range. Often rentals, especially cross-border rentals and/or underage rentals will come with geographic restrictions such as you can only take the car into neighboring states/provinces. If you wonder how they would know, pretty much every rental car these days comes with a GPS tracking device so that they can check for off-road and/or out-of-area usage. And bear in mind that if you break the contract by any such usage, or letting someone drive who didn't sign up as an extra driver at the time of pick-up, you are essentially driving a stolen vehicle and can be cited accordingly. I'm not saying or implying that any of the above conditions apply in your case, but you will need to check the details and keep the terms of the rental agreement in mind at all times.
