The Wisconsin DNR regulates burning in the
state.  You must obtain a burning permit before
doing any outdoor burning, except campfires.
To acquire a permit, you may call the DNR at
888-WIS-BURN (947-2876) or go to the DNR's
website.  Locally, permits may be obtained from
Dan or Carole Betts at 715-757-3683 or at the
Red Pine BP.  
These permits are free.
