The color-coded terminal ends of the two cursive initials are doing alot of work on this map. They point to the spots that Lynn and Frank want their guests to visit. This map is very "clean and mechanical" to fit their scientific personalities. A map of this sort isn't always possible as some initials are uncooperative when it comes to making them point in a certain direction. I do try to follow the rules of lettering as much as the rules of cartography.
