The reason I started this post because @Further made the comment that he was amazed at the heavy manufacturing that is in my little corner of the world.
When I was driving past Bucyrus now Caterpillar I started thinking. Some of the largest equipment in the world for the mining industry comes out of Wisconsin. The heavy duty trucks for the military is pumped out of a factory that's 45 miles from my house.
I was interested in what industry is in your area, what are they known to produce.
I worked for a company that only supplied about 15% of the mattress industry but we would make, assemble and ship 5 or 6,000 mattress a day....that works out to be around 1,700,000 springs a day.
