Please clarify what you mean Jaimela...
If I've understood you correctly, you mean "fun" as in, you know, something you don't go out of your way for? For example, just something you do while up at the cottage to kill a couple of hours on a hot summer day?
When you say "sport" do you mean something that one takes more seriously? For example, keeping up to date on the latest gear, tackle and techniques... going on frequent fishing excursions, always trying to catch more and bigger fish?
If that's what you mean, then count me as 1 for sport. (although it's a sport that I have lot's of "fun" doing)
