My biggest reservation about "street" tires is having one get cut or blowing out a sidewall. Street tires just aren't as well built. AT's are preferrable but as long as you have a full size spare, we can most likely get you on some cool trails. I will be leading Black Bear / Imogene and most likely Alpine Loop. If you run street tires, make sure you have a CB and let me know. I will put you up front behind me and I will make sure you stay away from the worst of it.
