Are You a Slag Shooter?

You're bored. There hasn't been a train for over an hour. The scanner is so quiet that you keep checking the squelch. It's too, hot, cold, windy, wet. The right-of-way is dull as dishwater, but you start snapping pictures anyway: scrubby trees, the ballast at your feet, a lump of old slag, whatever, it doesn't matter, they will all suck. The only hazard is filling up your card and having nothing when the train finally shows. Where is that train anyway?
