Dept of Public Works
Do you like to travel? If you do, you've probably come across places the Department of Public Works built. Many of the public roads, railways, and seas on the mainland were made by them.
Three of my favorite places they've done are the funfair at Pyri Peaks (make sure to explore the Tunnel of Love), Rizal (a great place to go with a friend or three), and the Linden Memorial Park.
It would also seem that D is for Darn. Or maybe Disconnect.
At least the message made me laugh, right?
