Why were the garage doors swinging open?

Ok, I got to the rehab house this afternoon and the garage/shed doors were swinging open. Well, this is an older building separate from the house and we hadnt even put anything in it yet. on closer inspection we realized why the doors were open.. The FIRE DEPARTMENT had opened them to put the fire out! Seems as if the plastic dumpster that the neighborhood shares in the alley had caught fire and which then caught the shed on fire...
geeze.. never boring!!
