When we travel we like to go "watch it made". Are there any good factory tours near you we should see?
Here in Central PA area you can walk the floors at the Harley Davidson plant in York, or the Mack Truck plant in Allentown. Most of the many snackfood places have tours, one of our favorites is UTZ potato chips in Hanover. There is always Hershey's Chocolate World, but its just not the same, its a ride through a mock up, you used to walk the actual factory, the smells were overwhelming.
In York every year they have a special time when many places open their doors to visitors that normally aren't, kind of like a Chirtmas Home Tour. It is usually in June.
