I did the RPAL with Dennis last weekend and the PAL this weekend, and it was a good course. He's a very humorous and knowledgeable instructor. Be warned, there's an awful lot of overlap between the courses, but that's not his fault. Speaking as a high school teacher with 15 years under my belt, his pedagogy is excellent for someone without a teaching degree - he understands how to use written text, visual medium, and auditory cues to get students to remember things both short-term and long-term.
Hey SgtMjr, nice to see another former Black Devil here. I was in '89-92, starting back when Mr. Boyd was still a 2 hook.
