Can we come check them out? And of course, absolutely, my dad invited him down and they met together with the Dickinson county local snowmobile club, the DNR, whoever else had to be involved, and everything checked out. Todd liked what he saw. The Dickinson County Snowhawks have done a tremendous job in organizing, putting everything together to get them to come down and everything's coming together and it will hopefully be a good event."
