The fire dept I work for does a couple offroad rallies a year in the west valley. It is a 30-/+ mile loop around Arlington, AZ. We were talking about opening it up to offroad clubs to help raise more money. The money we raise goes toward buying families christmas presents and nice holiday meals. Post up here if you are interested and I will PM you when I get an official day.
PS our next rally is tentatively planned for the beginning of December
