Purple paint has a new meaning in Pennsylvania under a law that just took effect in January.Landowners are now allowed to legally notify hunters and others that they're trespassing by painting purple stripes on trees or posts.The "purple paint" law is designed to ease a landowner's task of posting "no trespassing" signs, which can deteriorate over time.The purple stripes must be vertical lines at least 8 inches long and 1 inch wide.The stripes must be 3 to 5 feet off the ground, no more than 100 feet apart and clearly visible to a person approaching the property.Gov. Tom Wolf signed the bill into law in November. It applies everywhere except in Philadelphia and Allegheny County.Other states have already adopted a purple paint law. Paint manufacturers have formulated cans of spray paint and brush paint marketed as "no hunting" paint.The new law generated strong reaction on WGAL's Facebook page. What do you think?
