Summer community college teaching?

In our November "how can we help you?" post, Anthony writes:

Question: How does a graduate student find summer teaching opportunities? I would be happy to adjunct this summer at a community college.

Context: I'm currently earning a masters degree in humanities. For it, I'll take a couple philosophy-related courses. I'm actually halfway through a PhD in philosophy at a different institution; I'm officially on a leave of absence from my PhD program to complete this MA. I've completed graduate coursework at my PhD program. But my PhD program only grants masters degrees to those who exit the program early (which seems unjustified to me, but that's a different matter), so I won't have a MA degree until June. My only experience as a primary instructor was at a summer school, but I do have several semesters of TAing under my belt.

Good question, and I have to confess to not knowing the answer. I suspect it's easier to get teaching opportunities at a community college during the normal academic year, as there are presumably more course sections then. I taught at a CC for a couple of semesters during grad school, and if I recall I just applied when I saw an advertisement. But I never did during the summer, so again, I'm not quite sure what the answer to the OP's question is. Do any of you know?
