There is a train that runs through this town every morning at 4am. How do I know this, you ask? Well, you see my window faces the "main street" of town, which is where the train track passes through. Being a typical small PA town, there isn't even enough traffic to put in much for crossing guards & lights. Instead, the trains blare their very very loud horns for the duration of the time it takes them to pass through Grove City. These horns are so loud, that it is pointless to try to listen to music or talk to the person standing next to you. I would say we probably get close to a dozen trains passing by in any given 24-hour period. But every night at midnight and 4am I am lulled to sleep by the gentle music of the train's horn. You gotta love PA! (and yes, that was sarcasm)
