I like Red for Trails as they are he hardest. I also use Red for Hwys because they are Red with or without Tracks in MapSource R&R. The only files of mine that have "Hwys" are these types of "OHV" area files showing every legal route in he area. Perhaps Black for Blacktop would be better. I never use Cyan or Yellow because MapSource uses Yellow for "Selected" Track and Cyan for "Selected" Track Points.
