Gymkana, an exhibition gymnastics troupe, was established by Dr. David A. Field at the University of Maryland in 1946. While they have always encouraged a healthy lifestyle, in 1985 troupe members formally pledged to remain drug, tobacco, and alcohol free, and to promote that lifestyle to their audiences. They perform at local schools and Maryland basketball games, and conclude with a home show every spring. The troupe is open to all University of Maryland students of all (or no) ability levels. Gymkana remains one of the oldest groups of its kind in the United States.
