Are Sky Lanterns Legal In The States Of Minnesota And Wisconsin?

I've written about these before;  Sky lanterns have become increasingly popular as a way for people to celebrate events like weddings and holidays.  But are they legal?

The answer to this question depends on which state you live in.  Currently, 29 states make it illegal to sell or use sky lanterns. Minnesota is one of those states in which it is illegal to sell or use sky lanterns.  As of this writing, they aren't banned in Wisconsin - but - fire officials are pressing many of the remaining states to also pass legislation that outlaws them.

What's at issue is fire safety.  In the last few years, there have been many accounts in the news of these lanterns sparking structure and forest fires.
