If you want permission do not show up with a quad. Let the land owner know at a later date that you have a quad (if you do). We've had land owners bring out the game with his loader backhoe rather than let us us a truck on his fields. You can always ask later under what conditions you can use the quad.
Thomas, you really are a redneck! LOL! I'll bet that where impossible is from you can't go very far with a quad without breaking laws.
