This last part about the D&R canal talks about the special bridges that were needed to cross the canal and who had to take care of them. And if you're wondering if the canal is still in use, Sigrid answers that question. There's a special tribute at the end of the video for which you might want this link.

Annette talks about the Wild West, and takes us to a famous gold mining town in South Dakota that was an important part of United States history.

Both Sigrid and Barbara like grammar and they talk about some of their pet peeves. The also agree that grammar isn't the most important thing. Using the language to communicate is more important.
