Of the people who live off campus, most live in Benicia. Of the apts in Vallejo, the ones on the east side of town are the most desirable. You can find them in the apt guide as off of aston pkwy or Admiral O'callahan. Some students actually got into houses in some of the nearby towns. The farthest north I know of anyone living is Fairfield, which is nice. The farthest south I know of is just north of Berkeley, in Richmond.
If you wanna know more, E-mail me.
