I'm a Homeland Security/Homeland Defense (HLS/HLD) Analyst and I'm interested in collaborating with others who are working in my field and establishing some type of open source system for sharing Chem/Bio/Rad/Nuc (CBRN)exercise planning templates and scenario building tools and data. The basic idea will be to share non-proprietary information that is mutually beneficial. I'm open to ideas for specific kind of information that can/should be shared and am interested to hear others thoughts. Of special interest is the role of community in recovery and community resiliency.
