I've been working as a developer sans college degree for years, the real reason being that I've been working on the web professionally since I was hired freshman year of highschool on a workstudy position for my local school district.
Although I've considered getting a degree if I were to move to a more populated area (like silicon valley/NY), but I may even work without it if I moved as well. I've had success working in other large places (LA, Philadelphia) without a degree.
When a job asks me why I don't have a degree, I tell them the truth, which is that I spend my free time learning new technologies, (most of which are too new to be taught in college), and working on personal projects, which look good on my portfolio.
My advice to you would be to let them know you think that the web moves too quickly to justify spending a few years in college learning technologies that will more than likely be obsolete by the time you graduate.
The web moves quickly, and I truly believe you can learn more by creating personal projects that require mastery of a certain technology than you would learn by working on a curriculum that was created with a broad audience and created over the course of 6 months (in which many things change online) before any student was subjected to it.
Best of luck!
