Every night I seem to find myself watching train videos on youtube. I try to stop, I try watching kittens play and then some wise guy at youtube sticks a link to a train video in there.
It's like it knows.
"Hey, watch me make this guy click a train video."
Then, five minutes later, I realize I could just drive over to the track crossing and wait, or I can watch here anytime. It's like trains on demand. "Hey, check it out. I can have all the fun of waiting on a train crossing right here in my own living room."
