least 50 feet long is used for the event. Footholes or "pits" are dug for each participant at 20-inch intervals. The pits are dug with a flat front and an angled back. Women began to compete sporadically starting in the 1960s and became regular participants as sorority teams in the mid-1980s. Hope College The Hope College Pull is an annual tug-of-war contest held across the Black River in Holland, Michigan on the fourth Saturday after Labor Day. Competitors are 40 members of the freshman and sophomore classes. Formal rules Two teams of eight, whose total mass must not exceed a maximum weight as determined for the class, align themselves at the end of a rope approximately in circumference. The rope is marked with a "centre line" and two markings to either side of the centre line. The teams start with the rope's centre line directly above a line marked on the ground, and once the contest (the "pull") has commenced, attempt to pull the other team such that the marking on the rope closest to their opponent crosses the centre line, or the opponents commit a foul. Lowering one's elbow below the knee during a pull, known as "locking", is a foul, as is touching the ground for extended periods of time. The rope must go under the arms; actions such as pulling the rope over the shoulders may be considered a foul. These rules apply in highly organized competitions such as the World Championships. However, in small or informal entertainment competitions, the rules are often arbitrarily interpreted and followed. A contest may feature a moat in a neutral zone, usually of mud or softened ground, which eliminates players who cross the zone or fall into it. Tactics Aside from the raw muscle power needed for tug of war, it is also a technical sport. The cooperation or "rhythm" of team members play an equally important role in victory, if not more, than their physical strength. To achieve this, a person called a "driver" is used to harmonize the team's joint traction power. The driver moves up and down next to their team pulling on the rope, giving orders to them when to pull and when to rest (called "hanging"). If the driver spots the opposing team trying to pull the driver's team away, the driver gives a "hang" command, each member will dig into the grass with their boots
