I have Larry's book.....and I have to say its very good...and essential if you are considering a float hunt for anything.
(Disclosure; I've never met Larry, no connection)
I've got both of Larry's books. both excellent books. pick up the Love, Thunder, and Bulls DVD's too. Wayne Kubat builds the Bull Magnet which is probably the most used moose call in Alaska and his DVD's are great sources for learning to call and techniques for calling moose.
Good thread, ordered the book and a couple videos myself. Can't wait to start learning from them, one more thing to make me wish hunting season would get here sooner!
