Here are a few links that I find interesting:
FireEngines.net – The best website for model fire trucks.
FireRescue1.com – Great place to find the latest fire related news.
SAMatters Radio – Dr. Rich Gasaway has been a first responder for 30+ years and now he trains first responders on how to develop and maintain Situational Awareness and how to improve high-risk decision making. IMPORTANT STUFF!!
