If there were no signs or fences, could Sally still be charged with trespassing?

The presence or absence of signs or fences on a property does not automatically exempt individuals from possible trespassing charges. For trespassing to be established, it typically requires that a person knowingly enters or remains on land that is private without the owner's permission. If Sally knowingly entered the property, her awareness of the action is a key factor in determining trespassing.

Even if there are no clear markers such as signs or fences indicating the property boundaries, the concept of "knowingly" entering the property remains crucial. This means that if it can be shown that Sally was aware she was entering the property without permission, she could still be charged with trespassing.

The other options present scenarios that either mitigate or negate the possibility of trespassing charges, but they do not necessarily align with the standard legal principles concerning trespassing. For instance, being lost may elicit some sympathy but does not legally excuse the act of trespassing, while the private nature of the land is indeed significant in establishing trespass but doesn't address the critical element of her knowledge in entering the property.
