FJ Cruisers of Northern California
Hollister has 2 parks one for bikes and one for 4x4s, so they are separated. The crew that runs Hollister has spent a lot of time building up the 4x4 side like obstacle courses
I'm not a big fan of Raines, I think it is better for bikes, and I've seen and heard about about too much rig carnage there.
I've been to both and was not a fan of Raines. There wasn't much to do in terms of testing your rig. I would definitely recommend Hollister.
Definitely Hollister. You're done with Raines in 15 min and it doesn't feel right. Too sketchy.
You can spend all day at Hollister and still not see half of it. All levels of skill.
Whichever you choose, set up a trail run and I'm sure people will show up!!!
