It's back! GA Tuesdays is an event hosted by ZMP featuring different class Delta or Charlie fields every edition within the ZMP airspace. We will try to make this an every 2 week fun fly-in given that the date is open. Today's feature field is KDLH! Winter is over and the snow is gone. What's not to love? Come fly your jet, prop, or even helicopter, in or out of Duluth International Airport between 2300Z and 0200Z.
