In Maine we are blessed to have seemingly endless stretches of the great outdoors for hiking, hunting, snowmobiling and more.

However, it's very important to know where you can and can't explore. You certainly shouldn't assume that every piece of land in our great state is free to roam on as you wish.

The Maine Department of Inland Fisheries and Wildlife has issued a serious caution for outdoor enthusiasts. The message from their Facebook page tells us to look out for purple stripes painted on trees.

If you see them it means that you need permission from the landowner before wandering onto the property.

The purple paint on the tree doesn't just warn you that it's private property, it stresses that it's private property that you need approval from owner for, before you enter on to it.
