Ramblers
I've never seen humping or a rambler, I guess cuz I only go to small spots...but after reading about ramblers on this thread, I got the shiznitch scared out of me.
Cracked, you said...
"This raises several safety issues: One, a train that is backing up, or cars that have been humped off, can run you down without you ever hearing an engine."
Did you mean that you can hear them (ramblers), they are just nowhere as loud as an engine, or are they completely silent?
