Have you ever been to Fly fishing, when you use fly to catch a fish?
No, I've personally never been a fan of fishing. Haven't watched or tried anything since I was little.
It can be done in fresh or salt water. I prefer fresh water, Nature is more beautiful near rivers and lakes. 
Nature is indeed very beautiful. Very calming in those areas.  
I was fishing in St. Johns River last year, it is the longest river in the U.S. state of Florida
Only place I've ever tried fishing(When I was little) was at the Hillsborough State park
hoe was it, did you use fly rod, reel, and specialized weighted line for fishing?
