i was doing some target shooting in an empty gravel pit this afternoon. no one was around for miles and i didn't see any cars on the road in. i was setting up my targets and could smell smoke, but didn't realize thats what it was at the time. later on i could see smoke coming from a pile of something at the end of the pit, but it took me a few minutes to realize what it was. i walked over and it was smoldering blanket. it looked like it was wrapped around something, and i've watched so much CSI i thought it was body. nothing was inside though. it flared up and burnt up before i could douse it. i'm trying to figure out when it was started and why?
