Taggin' and Threadin'

Gobo was currently sitting on the edge of the fountain out in front of McDuck Manor, a piece of paper stretched across his lap. He drew a line across it, referenced a notepad in his pocket, then crossed it to another line at a precise angle. Filling in an area with shading, he moved to another, going back over a rough sketch that was there.

Map-making, it was a bit of a tedious process, but the payoff would be great. Once he was finished, the current tunnels under Duckburg would be completely mapped out.
