Has anyone been to the Cal 4wheel Winter Fun Fest in Grass Valley CA before? I'm going this weekend, first time. Any suggestions on what time to be there in the mornings? Where exactly are the trails (I don't think they're in Grass Valley, no snow there) located? What are the difficulty levels of each run (feedback from someone who has actually done the runs before?) Excited to be snow wheeling this Jeep for the first time! Any info is greatly appreciated! Hope to see some of you Jeep Wrangler Jl owners out there. I'll be in the Ocean Blue Rubicon license plate TOP 4X4.
