The Siren Board

So this is one of the bigger county wide siren maps I've made. Contra Costa County is home to the Richmond Chevron Refinery. The refinery cought fire and exploded on August 6th, 2012. The county has mainly OM-120s. They have some E-Class's, Cyclone's, a T-121, and a Whelen. Anyways, hope you like this map!
