BnM has a series of videos that I really like. Anyplace/Anytime Crappie, I think they are called. Each has ten or 12 segments (about 30 minutes each) with very specific information on different techniques on different lakes. Bass Pro has them in their catalog, and I think Grizzly Jig carries them as well.
