Minnesotans are one step closer to legally buying and shooting off a wider range of fireworks this summer. The Minnesota Senate approved a bill Tuesday to make aerial fireworks legal in the state. Current law limits consumers to sparklers and other toys low in explosives. The House version of the bill is awaiting a floor vote. Supporters say Minnesotans already buy larger fireworks in Wisconsin and North and South Dakota. They say allowing such fireworks within the borders would generate money from sales taxes and eliminate a barely enforced law. But critics point out that hospitals, law enforcement and fire chief organizations are opposed to a looser law. They say it will cause more injuries and property damage. If approved the bill would take effect on June 1st.
