I found the class through my local REI store (www.rei.com). It's called their Outdoor School.
It's a one day course called Road Biking for Beginners, or something like that. I was just lucky that they happened to have one in 2 weeks. I also tried looking into my local community colleges, but I didn't have much luck.

Thanks so much to everyone who answered my questions. You've been a terrific help!!
