A Bill to legalize more powerful backyard fireworks in Minnesota has made it’s way to Governor Dayton’s desk. The Minnesota Senate voted 48-17 on Tuesday to legalize aerial fireworks and devices with more bang than are permitted now. The bill expands on a 2002 law that let people set off lower-grade novelty fireworks. Dayton says that he is “genuinely undecided” on the bill after hearing from fire chiefs and others raising safety concerns. Supporters argued that Minnesotans are buying the fireworks in neighboring states and setting them off illegally back at home. The bill sets a five-week window starting June 1st where the devices can be bought and used. It also would give cities power to enact some local restrictions.
