Ours came in a kit, but you can usually get anything you need at Farm Tek out of Dyersville, Iowa.
They will charge you an arm and a leg for delivery, so plan ahead, order what you need and make it a Day Trip to pick up your order for free.
We had to buy some more panels and we had a nice lunch, stopped to see ‘The Field of Dreams’ and saw a lot of pretty countryside there and back. We also stopped at Indian Mound State Park and that was REALLY cool!
And, driving over The Mighty Mississippi is always awe-inspiring! :)
