I say take the chance. It is true that it is easier to get a job once you are in the area. I also just graduated with a CS degree and moved cross country (chicago to san fran). I had a very crappy job lined up since it was extremely hard looking from across the country.
Within 4 months of being here, I have obtained an amazing job and have gotten many other interviews. Seriously, close proximity helps.
Good luck on everything. Its an exciting time
