I watched a "Train Hopper" video and the Cops told the trespassing arrestee's, that they were lucky that they got arrested and taken to prison outside, in Akron, OH, as the vandalizum and theft rate in Chicago yards, would have lead to them being murdered by Chicago hoodlums, if they had made it train hopping into Chicago yards.
Freight yards are NOT "nice" places at all, and places like Selkirk, Oak Island, and Chicago etc, etc, areas are treacherous places, even for yard workers and police, endangered from being shot.
