I have combed over the net and have found nothing. Minus PR's by CGAQ and questions on other boards and sites. Even saw one of your questions on a different site in regards to the track.
I to have called with my limited spanish and can not find anyone that knows squat... just hold on and answering machines with no return calls.
It would be easier to find out whats at Area 51 or if there is still gold in Fort Knox.
I keep the faith, but maybe you can find out more than I have been able to.
