1. Get a small handful of flat rectangular wooden pieces (like Catan road). mostly natural colored, but have 2-3 sets of paired color-matching that can be marked or come in unique colors.
2. Lay out Locations appropriately.
3. Place the natural wood pieces between Location cards to indicate travel routes that are immediately adjacent to each other.
4. Parse (and teach new players) potential travel routes so much easier.
Some options this allows for user created scenarios:
-Mark an arrow on one piece and use it to indicate one way travel only.
-Use a pair of colored pieces to indicate a shortcut between two Location cards that are distant on the board.
-Pick a Wild/rainbow color and use it for the inevitable "you can go to any location when you depart the Plains of Leng" option.
For regular scenarios, using this method will help with visualization a lot better (for some) than trying to parse the tiny icons.
For user created Scenarios, using this method will allow remixes of scenario decks and make for some interesting variants that rely more heavily on the keyword functions.
