Trespass law modified to allow purple markings.

HF 944 amends Minnesota's trespass law to allow landowners to use purple paint markings as a legal alternative to traditional "no trespassing" signs for restricting outdoor recreation on their property. The bill specifies that purple markings must be vertical lines (at least 8 inches long, 1 inch wide) placed 3-5 feet from the ground, spaced no more than 100 feet apart on forest land or 1,000 feet apart elsewhere. This directly affects landowners seeking to manage recreational access and users who might enter marked areas without permission. The change provides a standardized, visible method for landowners to communicate trespass restrictions without requiring physical signs.
