Montana was the last state to raise its legal drinking age to 21, doing so in 1987 after a federal law was passed that required all states to have a minimum drinking age of 21 or risk losing federal highway funding.
Liberty County, Montana, is located in the north-central part of the state and has a rich history that dates back centuries. The area that is now Liberty County was initially home to various Native American tribes, including the Blackfeet and Assiniboine tribes, who relied on the land for hunting and gathering.

The first European explorers arrived in the late 18th century, with the Lewis and Clark expedition passing through the region in 1805. The fur trade played a significant role in the early development of the area, with fur traders and trappers establishing posts along the Missouri River.

The establishment of Fort Benton in the mid-19th century further spurred development in the region, as it became a vital trading post and transportation hub for settlers moving westward. Montana became a separate territory in 1864, and Liberty County was officially organized in 1920, named in honor of the ideal of liberty.

Agriculture quickly became the predominant industry in Liberty County, with settlers primarily engaged in farming and ranching activities. The rich soil and ample water supply provided ideal conditions for raising crops and livestock. The construction of railways in the late 19th and early 20th centuries further facilitated the growth of agriculture by providing efficient transportation for goods to markets.

Today, Liberty County continues to be primarily rural and agrarian, with agriculture remaining an essential part of the local economy. The county is known for its production of wheat, barley, canola, and beef cattle. The area also offers stunning natural beauty and opportunities for outdoor recreation, with the majestic Rocky Mountains to the west and the diverse habitat of the Montana prairie to the east.
