Eltopo, I don't believe you mentioned what time you arrived at the ranch. Mike doesn't like people coming there after dark. And he hates some of the regular users who always use the "free" road.As you've seen and heard here, he is subject to MASSIVE mood swings. Please note that he always carries a gun when he's out and about. If you play by his rules you'll be fine.
Also, I believe the alternative "free" road off to the right from the Ranch is 4 wheel drive only, but I could be wrong.
