Skip Sacto, it's boring flat sprawling suburbia ala compartively sized midwestern city. Old Sacto is a joke. Nightlife is weak--just blah. A few strip clubs are really good though--up there with the majors in quality. All things suburban (i.e. shopping) is good as expected for such a new sprawling city.
I lived there for many of my young teen years. I couldn't wait to graduate from H.S. and get the fVck out of there FAST forever!
Spend any of your free time and go visit SF (very cool city, lots to do!--90 minutes away by car), Napa (wine valley, very interesting places to visit--90 minutes), or Lake Tahoe (nature, skiing, Vegas style casinos/shows--2 hrs away).
Sacto/Central Valley Cali. is not what most out-of-staters think of California....so skip it or be dissapointed if you invest the time getting to know it when you could visit MUCH more interesting places.
