Concept model

I found it in my brain to make a conceptual model. I have never done this before. Woo!

On the left is the ideal path that skiers would take down the mountain. No obstacles, no choices to make, no intersecting other skiers' paths.
On the right is what I am trying to accomplish. I want to create situations that allow people to take a different path than they normally would. Some paths are more convenient, and some less, but they are there to create a different experience.
