JTN-10 are you saying you need written permission on private land. 2nd you can't use a motorized vehicle to shoot from if vehicle is not moving from effects of motor.3rd are hogs considered a game animal or a vermin. In Oregon I can hunt rabbits,sage rats and coyotes from a moving vehicle day or night with written permission from a land owner as long as I'm on his property and not a BLM,county or state rd going through his property.
