"5.11.4 Regional Championships may be entered by any driver from the host region or adjacent regions which share the same border. Drivers are allowed only one Regional Championship title per class per scale per calendar year. A title winning driver may only enter a different class or scale at subsequent Regional Championships for the remainder of the calendar year."
This rule was changed to the above for 2006. You can race as if you were in the region, provided you are in an adjacent region. I think you cannot race another race of the same type if you win the title.
