I was coming across the NS mainline this morning near Lowell, NC. I looked at the signals (habit) and looked both ways before proceeding. Clear path, no gates down, no trains. Just as I started across the tracks some one blared out with a LOUD horn. SCREEEEEECH! I slid to a stop! That near 'bout scared me out of a year's growth! Sounded JUST like a train. Guess somebody thought that would be "funny". I didn't! Its NOT funny!
