hello dear have you ever go fishing? like fly fishing, is an angling method in which an artificial "fly" is used to catch fish.  
I have been fly fishing once with my brother.  I have to say I was terrible at it, but he was pretty much an expert.  Are you a fly fisherperson?
no, but my friend is. do you know that the fly is cast using a fly rod, reel, and specialized weighted line.
I didn't know that.  Are there different types of fly's that are used?
the  fishermen use the once that  resemble natural invertebrates, baitfish
