Mardi Gras is an annual fund-raising event staged by the Pleasanton Juniors. King and Queen Candidates hold moneymaking events and the candidate who raises the most money wins., Last year we raised $12,800 for the senior citizens' transportation system and $1,000 for youth counseling programs. The climax is the Mardi Gras Ball. Over 500 people come to drink, eat, dance and celebrate the coronation.
