Yup, that's Big Bear for you. Though more an attestment to the poorly equipped and poor judgement of warm weather SoCal drivers than anything. As most cars are equipped with summer or all-season tires that are not appropriate for this kind of weather. I was one of them 20 years ago, before I decided I needed the right tools if I was going to make winter sports a regular hobby. Chains get old fast.
I built my rig to play in this region, without chains. With the right consideration to AT tires, the 200-series is a beast and way beyond what's showcased here.
