Rubber combusts spontaneously. Every educated person knows this. The smaller the rubber particles and the larger their surface area, the more prone they are to spontaneous combustion. These rubber "granules" are lying in a pile. This is an invitation to spontaneous combustion. We all want to blame "kids" but likely, this is the result of ignorant persons storing a highly combustible material without regard to safety. My advice is to get the geniuses responsible for this situation to spread the granules on the track, right away.

Good grief! The stupidity! The abysmal ignorance!
