Ever considered opening up your farm to tourists who want a taste of farming life? Check out Farm Stay US. This site is devoted to providing information on agritourism -- including information for farmers on what to consider when starting a farm stay.
There's definitely a lot to consider -- you'll need liability insurance, for starters -- but farm stays can be a fun twist to your lifestyle and add income to your small farm. Generally, guests can help out if they want (although certain tasks, such as driving the tractor, are typically off-limits), but they don't have to feel obligated. They can just soak in the farm atmosphere and the natural beauty surrounding them.
It's an interesting idea, and one that is gaining in popularity. Do you offer farm stays, or one-day farm tours? Do you plan to develop more agritourism opportunities on your farm?
