Move away for community college?

I am a senior and will be starting college in the fall of 2012. It has been my dream to move to San Diego right after highschool and go to SDSU but I can't afford the tuition and don't have the required 2 years of a foreign language to get in. Rather than being stuck at a community college in my hometown, i have been considering moving down to San Diego after graduation, getting an apartment with a roommate or two, and attending the community college down there. The only problem is finding a job down there, getting an apartment, and saving up money to survive off of until i get employed in San Diego. Is it worth going through all this trouble to move down there or should i just attend my local CC? And, in the end, would it be cheaper, as expensive or more expensive to live down there in an apartment vs. going straight to SDSU?
