The Village of Big Rock has made a great effort to make the level crossing in town to be a "no horn" crossing. New sidewalks, fences, safety rails and road dividers. As someone that lives VERY nearby, this is a nice feature, despite some of the wackiness of the new road layout. Just the silent passage of tons of rail cars! 
Seemed like a good enough reason to add another Big Rock cache into the mix. Happy hunting.
