Sac is coo...
If you dont know anybody or dont put yourself out there it could get boring, but as long as your willing to get out the house and not just sit at home and complain about how there is nothing to there is a lot of fun shit to get into. Lots of different clubs and shows to go to every weekend, hella bitches, a few malls to go shoppin at, ect ect.
If your worried about gangs and shit like that stay away from hoods like oakpark and Del paso Hights. I mean its kind of hard to avoid gangs in SAC but as long as your not out there actin dumb shit should be all good. If you want to live in a coo spot with lots of shit to do stay downtown or midtown, i'd advise to not live in Elk Grove or some suburb like that cuz shit is boring as fuck and far away from everything.
