Ridiculous people

If there is no easement you can go the opposite way on them , the road is old enough to be claimed as permanent but not mapped as such so shrink it down to 5 ft wide with removable posts at the entrance and explain to the other users that one guy is ruining it for them, until they sort it out amongst themselves you are planning on using"your land " for something else and they'll just have to buy skinnier trucks,Why fued with them when it can be amazing what turning them on each other can accomplish I bet he not only apologizes but pulls your trailer out for you 8)
