If you were out in the woods, there were no houses or farms or anything in sight, you knew for an absolute fact that you didn't cross a posted boundary to get to your current location, and were confronted by some guy claiming you were on his property? Like some random stranger claiming that nature belongs to him and you've made some kind of mistake by simply walking around minding your own business? As though the onus were somehow upon you to magically know accurate and up to date property boundaries and juxtapose those with every step you take on undeveloped wilderness almost devoid of distinguishing characteristics labelled on any map, and to do this every single time you go outside, rather than upon the landowner to simply maintain a perimeter of signs?
