Well, it was a nice break, but summer quarter starts this week. Since I'm a non-traditional student with a full-time job, I thought I'd take a few classes over the summer. If I didn't, I probably wouldn't be able to motivate myself to return in the fall.
One good thing about classes over the summer is that they tend to be a bit smaller: everyone else is enjoying their summer vacation. Plus, the quarter is broken up into two "sessions," each session being half the quarter. Some classes run the full quarter, but many run either first or second session. This allows me to get a couple of less-enjoyable classes out of the way pretty quickly, keeping them as painless as possible :)
