Multiple Polygons into One -- Averaging best lines

[ScottJones1]

I think this is a simple fix, I just cant remember the tool or correct process name.

We have a new mtn bike circuit. Due to the excessive trees the breadcrumb map is disjointed. I would like to take multiple polygons, or even the lines from the same polygon (2 laps leaving 'collect' on) and blend them together.

My thinking is the lines will come together and better reflect the course.

So one possible workflow to consider:
1.  If the data is in multiple feature classes, you the Merge (Data Management) GP tool to merge them into a new, single feature line feature class.
2. Using the new, single line feature class, use the Snap (Editing) GP tool to pull near coincident enpoints and vertices together using a small tolerance.

If you have the Production Mapping extension, you can go a little further...
3.  Create a corridor for all passes by using the Buffer tool by a short distance that matches the trail width under tree canopy.
4.  Dissolve the buffer polygons so you get one continuous corridor polygon.  Then use the Polygon to Centerline (Topographic Production) GP tool to get a new centerline.
