I am trying to produce some trail maps in UTM Zone 11 North, which is standard for my region. When I look at examples of other trail maps produced in this projection, the meridians, parallels and UTM grids are all perfectly parallel or perpendicular to the data frame. That is not the case when I use this projection. The parallels, meridians, and UTM grids almost always appear at a slight angle to the data frame (See example-look at the meridian on the far right side of the map), particularly when producing maps near the edge of the zone. What can I do to make them perfectly parallel or perpendicular?
