In 2020, many people in the United States found an escape by going out into nature and open places. Hiking trails, parks and other outdoor spaces were very busy with people searching for fresh air during coronavirus health crisis restrictions. People, who were staying at home and whose gyms were closed, took their exercise to the “Great Outdoors.” Sports such as hiking, biking, cross-country skiing, snowshoeing, camping, tennis, and golf all became more popular. In 2021, that seems to be continuing. People are still finding ways to play outdoors within coronavirus restrictions and stay-at-home guidelines. The Outdoor Foundation is part of the Outdoor Industry Association, a trade group. It released numbers comparing Americans' outdoor activities in 2019 and 2020. The group said 8.1 million more Americans went hiking, 7.9 million more went camping and 3.4 million more people went freshwater fishing in 2020 than in the year before. In 2020, the foundation’s research also found a 52.9 percent increase in outdoor activity for most age groups and all income levels.
