It varies. We average 2 calls a day under normal circumstances, but my town is an evacuation center, so our population has a tendancy to double. The population spur wouldn't be such a problem, but the evacuees often get quite... rowdy... Especially if they come from a "Dry" area where alcohol is banned, and then get their hands on some when they get to our town. Drugs and violence are also problems with evacuees. Call volumes can triple, quadruple, or more.
