Bill Gronseth - the Superintendent of the Duluth Public School system is mad - and he has a good reason:  A suspicious fire over the weekend damaged the playground at Lester Park Elementary;  this event marks the second such fire in the past six years.

The fire this weekend happened Sunday night around 8:00 PM.

Gronseth took to social media to call out the vandals and to solicit help from the public.
