The Walk throughs are aslo good that are on the IMAC site. Plus just hanging with guys at the field. You have at least two fields in your area with very active set of aerobatic pilots. El Toro and Prado both have a number of aerobatics pilots flying at them. You have to be a member or invited guest to fly El Toro, but you can fly at Prado as long as you are an AMA member and pay the $10 daily fee.
