I do the majority of my fishing from my boat, and I fish mainly for bass, stripers, and channel/flathead cats.And I use my fly rod from the boat, as well as bait cast and spinning rigs.
Two instructional DVD's that you MUST have getting started fly fishing.
1. "Basic Fly Casting with Doug Swisher" from Scientific Anglers.
2. "Fly Fishing for Bass and Panfish with Skip and Carol Morris" from Fly Fish TV.
Both are available from the Bass Pro Shops online catalog under "books/DVD's".
These will greatly accelerate the learning curve for you on the path to enjoying fly fishing. Enjoy, and happy fishing.
