Forest Hill OHV. Any one ridden it?

Anyone ride forest hill OHV? Rider planet says it’s limited to 50” trails but Im not sure about that.
Looking to ride on November 10/11 and need a good spot up north. Possibly hollister but it is south and I head north from the city to go home first, so it’s not ideal to double back.

Anyone have a recommendation to ride somewhere within 3 hours or so of Petaluma?

Everyone welcome to join to the ride of course! Will be doing a bit of geocaching as well on the ride.
