As per Great Lakes Classic Tractor Pull:
Sadly, we have to announce that we will not be holding the Great Lakes Classic this year. We had some issues with sponsorships not being fulfilled, and other behind the scenes issues. We know that this is disappointing to a lot of people, just as it is disappointing to us as well.
We felt that it was a better decision to cancel the event, instead of putting on an event that would be extremely sub-par to our puller’s expectations. We appreciate your support and understanding. Good luck to you all in the 2017-2018 season for NATPA!
