I am going to be moving to Tucson in April and i was wondering if there are any riding areas around there. If so what kind? I am currently setup for woods riding in PA. Basically i am concerned about my tires. I am running Mudsharks on there now. Is it sand? ot is it more hard packed? Also is it wet, I am thinking about getting the K&N clamp ons. (I know that it doesnt rain much.) Thanks for the help in advance.
