I almost hate to admit this, especially seeing that I used to live 2 miles from the base of Mt Lemmon right on Catalina Hwy. But I've ridden my bike up and down Mt Lemmon about a thousand times back in college and hiked at best a mile off the highway in order to get to my rock climbing spots. Heading down for a weekend with my folks and would like to do something that's 3-4 hours long (6-10 miles or so). What's a good spot that won't be too crowded if I get there early in the morning?
