Something else to consider:
In my experience at two different community colleges, you can expect to adjunct for six years (conservative estimate) before you're seriously considered for the full-time gig. Also in my experience, "full-time gig" is far more accurate a description for the CC level than is "tenure-track job."
In theory, you could get a full-time gig after adjuncting for three years (or perhaps even fewer), but that'll depend on where you're teaching, of course.
I would go on about everything I've experienced at the adjunct level, but I don't really feel like writing a novel right now. If anyone's interested, just PM me and I'll write you a massive epic.
