Huge Pileup Downtown Wrecks Gravel Trucks! Authorities Report: Gravel Appears Unharmed The area around the regional headquarters for Gray Gravel Co. has been closed to civilian traffic after a massive accident involving several gravel transport trucks. The area needs to be clear of pedestrians and drivers, as "cleanup crews" have been mobilized to secure the precious gravel. There's a sewer with a current that takes you behind the point, that may change to a subway or even a generic tunnel in future versions. Let me know what you think! Huge thanks to Rexy for all his awesome models.
