Agritourism is all about re-imagining the family farm. We traditionally use farms to tell participants about the farm's history and talk about animals and horticulture.
Why not use farmland to host an event. Recently, I saw a photo of a bride with a big red barn in the backdrop. Photographers look for backgrounds and farms have a lot to offer. A photographer could host a workshop on your farm with plenty of outdoor landscapes.
Why not have a barn wedding and a reception to follow. Or host a birthday party or family reunion.
Consider your farmland as an open canvas and explore the many possibilities.
