Megret recommended checking out this site that lists factory tours by state. Guess what was first on my list from that site? Cerrata candy factory in Glendale, AZ. If you are an "I Love Lucy" fan, you may remember the scene where Lucy is working in a candy factory and is wildly stuffing the confections in her mouth. This is the place.
The tour was free. But that wasn't the best part: they were oh-so-generous with the chocolate. I think I ate four pieces. Mr. Intensity and his friend were WIRED by the time we left.
I'm thinking we will have to go back again, soon!
