Big John’s Farm Market & Greenhouse in Lowell, Indiana scales up the patriotism for the 2026 autumn season with a spectacular tribute honoring America's 250th anniversary. Cut into a sprawling five-acre field, the family-friendly corn labyrinth features an intricate national landscape carved precisely straight into the tall stalks, highlighting a waving American flag alongside a majestic eagle head. Explorers and families can spend a sunny fall afternoon weaving through more than two miles of winding pathways divided into separate challenge loops to hunt for hidden checkpoints. Outside the towering walls of corn, the nearly seventy-year-old family farm keeps the harvest festival packed with premium agritourism highlights, including tractor-pulled hayrides, a massive pumpkin patch, hillbilly basketball, a giant slide, and fresh-baked donuts made daily.
