When my wife and I started dating, I made sure she knew that I had a few hobbies: hunting, fishing, and golf. Since our time together she has come to like all three (she already was a hunter, but didn't fish or golf). I do like to golf and fish more than her, but she actually likes to hunt more than me.
The best thing about getting her into fishing and golf -- I never have to explain when a box with a new "toy" in it arrives. Heck, when I tell her I am making an order, she usually puts a request in as well...it makes b-day and Christmas shopping easier for me.
