Fly fishing is an angling method which my grandfather taught me. Its quite a good technique. 
Oh neat, I've always found that interesting. Where are fly fish located? We mainly have bass where i'm from
It just refers to casting using a fly rod, reel, and specialized weighted line.
Hmmm gotcha. Well what's a fun fact about it?
Well, casting a nearly weightless fly or "lure" requires immense precision. Not a fun fact, but still interesting.
No that definitely counts! I wasn't aware the lure was so leight. That must be difficult
It is! Fly fishermen use hand tied flies which are even more complicated
Tied? So what are the flies made of?
