All coal mines have rats. The rat was the miner's best friend at times. When the overhead rock in the mines started moving, it was near impossible for a miner to know it,unless it was getting ready to fall. The rats knew though; soon as it happened, they would start rapid movements away from that dangerous area,and give the miners notice. No miner I know would ever kill a mine rat. They were friends, and sometimes rewarded with part of the miner's lunch for gratitude. Shelby ************************************** Check out AOL's list of 2007's hottest products.
