Anyone can file a lawsuit for anything. Filing a lawsuit that doesn't get immediately dismissed by the judge because it has no merit, is a different question.

Anyone can file a lawsuit for anything. Filing a lawsuit that doesn't get immediately dismissed by the judge because it has no merit, is a different question. ----- In the Northern New England states (VT/NH/ME) that have a sort of freedom to roam codified in law (basically - unposted, undeveloped property is generally free to access for low-impact uses like hiking without requiring permission) - there is broad liability protection provided to the property owner. For example, the law in VT for liability in that land access situation is only if the injury that occurs is "....the result of the willful or wanton misconduct of the owner." (and has further exemptions from even that if the injury is with regards to accessing equipment/machinery/personal property - which you're not entitled to access). You pretty much need to be setting traps or creating some truly absurd unnatural hazards to be at legal risk.
