Twin Falls, Idaho ( KMVT-TV / KSVT-TV ) It was a big day for the City of Twin Falls as grand openings dotted the city. Over at the Sunway Soccer Complex the brand new First Federal Bank Park officially became the newest addition to the city. None of this could have come to be if it wasn't for the men and women from First Federal Bank. That's because First Fed literally built the park and handed it over to the city as a gift. For the City of Twin Falls, a gift of this magnitude is something they could have never imagined. Now that the park is officially open, that doesn't mean the work is complete. Crews are now working to build a splash pad out at the site. That's anticipated to be open sometime in mid–June.
