ST. PAUL, Minn. (AP) -- Minnesota snowmobile owners, beware: The North Star State may have the highest number of snowmobile thefts in the country.

A new report by nonprofit National Insurance Crime Bureau found that more than 300 snowmobiles were stolen in Minnesota from 2015 to 2017. Reports say it's the state with the highest number of snowmobile thefts in the U.S., followed by Michigan.

The report says almost half of the 20 U.S. counties reporting the most snowmobile thefts are located in Minnesota, led by Anoka and St. Louis counties.

Bureau spokesman Frank Scafidi says snowmobiles are vulnerable to theft because they're often stored in places that make them easy to haul away, such as trailers. Scafidi says they're also easily hidden.

More than half of Minnesota's stolen sleds are never returned.
