Looking for information on Leslie Nelson's book and DVD Really Reliable Recall, I came across a company that provides CDs of conferences and seminars including APDT's US conference from 2002 to the present.
Sessions, such as Nelson's, are available individually for US$14.00 or you can purchase the whole conference. They don't provide any details on the session, just the title and speaker so you have to either do some research or take a chance. Jean Owen - Advanced Agility Handling Skills with One Jump - sounded worth buying on spec, but a few moments Googling revealed Owen's expertise.
Might be something to listen to on those long drives to trials.
