SALT LAKE CITY — Utah's top political leaders and representatives of several outdoors organizations in the state say they support a bill that would facilitate a federal-local land swap in order to extend the Bonneville Shoreline Trail. It's considered a step forward in the ultimate goal of stretching the Bonneville Shoreline Trail from Utah's northern border with Idaho down to central Utah. Rep. John Curtis and Sen. Mitt Romney announced Tuesday they had reintroduced the Bonneville Shoreline Trail Advancement Act in Congress. It's the duo's latest attempt in trying to secure federal land to extend the trail. The bill calls for the release of 326 acres of wilderness within 20 "small locations" between Salt Lake and Utah counties that would "accommodate the advancement" of the trail within those counties.
