In the Ravenport map, you can find a car partly submerged in the water underneath the bridge, giving the appearance that someone crashed their car in the river, although there is no body or anything else unusual about the car.
In the Ravenport map, if you go into the windmill, you can go through a gap in the floor to access a hidden area. It is a small cave-like area with a chair as if someone was relaxing there. The cave then leads outside to another part of the map. It can be accessed from either spot.
In the Ravenport map, it is possible to find a broken arcade machine for a game called “Jet Set Farming 2148.”
