That sucks, but as you stated " It's on you". Mistakes are definitely made from time to time, but sometimes they are costly mistakes. I always use " ON-X HUNT" when I go hunting. I can look right at the app and shows me the property boundaries, who owns the property and whether it is public land or private land. It also shows my position, so I know where I am at and if I am still on land that I have permission to hunt on and how close I am to the boundary. If you just purchase it for the state you are hunting in, it's not expensive at all. Way cheaper than a trespassing ticket! Well worth the money to always know where you are in conjunction to property you are not allowed on.
