That's a 500 lb propane tank deliberately set on fire for a training exercise. My baby child is in the group of 4 on the right, up front, holding the hose on this fire. I say prayers every day for his safety and every one of the kids he's training with. He's a junior in the Fire Science program at Lake Superior State University in Sault Ste Marie MI.
I also silently say a prayer for the safety of all the first responders every time an emergency vehicle flies down the road with sirens blaring.
