actually you have it a little wrong.
the DNR is opening up more forest roads to orv use in the lower.
you still cannot ride on the snowmobile trail with an ORV during the snowmobile season december 1st till march 31st legally.
including snowbikes not manufactured as a snowmobile .
I’m thinking they would tear up the trails more than a sled. It’s bad enough hitting moguls left behind by guys on sleds stopping on trail then giving it.
