When was the last time you created a map for treasure?! You don't need the treasure to create the map, because everyone knows the path IS the goal! And Thomson is definitely all about the path! Thomson uses chalk on sidewalk to note how to find important things like rocks from Mars and Venus. So if you are walking around in San Francisco, keep an eye out, maybe you will find Thomson's cartography!
