Adjacent hiking trails

I am mapping a nature preserve with 3 different trails. At certain points the trails merge into one, but on the map I would like to show them as three lines right next to each other when they merge. Is there a way to do this other than moving the vertices by hand?

Mapping Center Answer:

At this time, there is no autmoated solution for you.  Even if you use cartographic representations and a free override to offset the lines so that the mapped display has the modified geometry but the source data remains the same, you would still have to "manually" edit the location of the lines by pulling them off of each other. 

However, you will be pleased to learn that in ArcGIS 10 there is a new set of graphic conflict tools, and one of them  is "Resolve Road Conflicts".  This tool "resolves graphic conflicts among symbolized road features by adjusting portions of line segments." This tool is typically used when producing relatively large-scale products where it is preferable to display divided roads with multiple lanes that are visually distinct; however, I think it would also work in the situation you describe.

So be sure to install 10 as soon as you get it and let us know how this works for you! :-)
