Only a single iron handrail provides protection. Keep in mind that these rooms are the areas where you may encounter gaping holes in the floor. There are many great views of the city skyline all the way up, too. There are many old, decayed rooms to explore on the journey to the top. On your journey to the top, you can navigate your way to a large room that sits atop the silos.
Large windows flank the room, making it very pretty at sunset.
It is probably 60-70' long by 30' wide. Even my D-Cell Maglite would not pierce the darkness enough to see the bottom. There is some cool machinery on tracks in here that once moved along the floor to pour stuff into each silo. You are probably about 20 storeys up here. Watch for bolts in sticking out of the floor.
