1. In 1858, the Great Blizzard of 1858 began on October 27th and continued for three days, dumping more than three feet of snow across Vermont and other parts of the Northeast. The storm caused significant disruption to transportation, communication, and agriculture in the region.

2. On October 27, 1870, the first passenger train arrived in St. Albans, Vermont, marking the completion of the Vermont and Canada Railroad. The railway played an important role in the development of St. Albans and opened up new markets for Vermont's agricultural products.

5. In 2018, Vermont became the first state in the country to legalize the possession and use of recreational marijuana through legislative action rather than through a voter referendum.
