I was in the same boat as you, having had a decade of experience making web sites and programming for NSCA Mosaic, but with no schooling to speak of that was relevant, no-one in my home-town would take a second look at my resume. I moved to NYC (but know that SF is similar, regarding qualification judgements), and found that everyone I talk to in the tech industry cares about what you're capable of, not what's on your resume. Now I'm a director at a fortune 500, and teach at one of the most prestigious design schools in the country. I still don't have a degree.
