Perhaps you prefer sporting events that involve teamwork.If so,you might consider attending the American Wife Carrying Championships in Maine. In this event,each participant navigates a difficult obstacle course that includes an 18-foot(6-meter)long pit filled with 3 feet(1 meter)of water,a downhill run on grass,and two log hurdles. The catch? He must do all of this while carrying a woman (though not necessarily his wife)on his back.
