Think I'm good to go on the 27th.
Question, does the OHV Red/Green sticker program apply to Hollister Hills? I'm not required to have one since my Rig is registered outside of CA (WA) but I wouldn't want to see anyone get a ticket out there.
You can't ride in the Vehicular Park, and can't drive in the Bike Park. And yes, the Red/Green sticker thing applies in the Bike Park.
