I have suggested "Tapping A Blast Furnace" but I am here to let you know again that it would make a interesting show since I have worked there years past and know the drama involved in the process. Also recently on vacation I went to the Mount Washington Cog Railroad,,just look at their web site. Love the show
I rode the cog railroad up Mt. Washington about a year ago. That sucker blows soot everywhere! I think I was picking coal dust out of my hair for a week. It was worth the view though!
