Yeah I never thought of the potential for "new" parts like 292's. The satellite image below shows some older sections of this guys empire. It is no telling what may lurk in the brush nd thickets. I noticed one of the buses had been painted with the words "every bus has snakes under them" for some forewarning. Looks like a fun place to explore.
