I have a strong affinity for tours of all kinds, and I have a feeling this love affair with behind-the-scenes knowledge comes from your neighbor and mine, Mister Rogers. Mister Rogers loved going on tours and sharing the experience with his viewers. While doing some factory tour research, I came across the site Factory Tours USA. This is, perhaps, one of the greatest Google finds I've come across. Click on any state, and get a full list of factories open to tours. Some of my favorites include:
Harpoon Brewery, Boston, MA
