Over the next couple of years, I'm going to be flying in and out of the Duluth Airport. Since my travel is going take me there for 4 to 6 weeks at a time, I thought I would bring a car out and leave it there to cut down on the cost of a car rental. The down side to this is when I fly home the car would sitting at the airport for again 4 to 6 weeks, before I came back again.
So what I'm looking for is either free parking [I know this is unlikely], or somewhere with a better parking rate then the airport is offering. Any ideas.
