Clear skies and no rain are a rarity this time of year in the Pacific Northwest, but freezing temps would make traction scarce around the hilly landscape. Washougal soil is already unforgiving, composed of very hard packed clay with a lot of imbedded and exposed rock. The dirt on the MX portion of the track has a lot of off-site additives, which allows for more moisture absorption. This is an enhancement in the summer months, but when frozen it transforms into chocolate colored asphalt. Before the first race began, it was clear that screws or studded tires would be required to have a controlled ride and any shot at a class win.
