You can take a car along this as it is a maintained, graded dirt road. It usually has some sections of pretty rough washboard and can get muddy and rutted when wet. If you do decide to bring a car (or really any vehicle, but mainly I'll direct this to cars) running street tires, low ground clearance ect. there is a greater possibility of getting a flat tire, damaging your suspension and/or your undercarriage. As stated in the opening post, we require vehicles with 4WD. Generally when we say that we are talking SUV's and trucks, but for this trip we'll accept cars with 4WD and decent ground clearance such as a Subaru or Toyota Rav4. If you do decide to show up with a 2WD car, thats your choice. We won't necessarily turn you away as this is an "open" event and a public road, but we would strongly recommend bringing something else.
