(Fargo, ND) -- A new study shows how much the Fargodome contributes to the local economy.  In the first economic impact study of the Fargodome in 18 years, data shows the Dome put in more than 63-and-a-half-million dollars each year over the last decade.  Fargodome officials say the three biggest events that drive revenue locally are amateur sporting events, big-name concerts and North Dakota State University home football games.  The study also shows annual economic impacts have grown by 21-percent since the last economic study conducted on the tenth anniversary of the Fargodome in 2002.
