You are screwed. She will be wanting to go fishing with you every time. She will also sneak out on fishing trips while you are working hard. You will need to spend between a $500 and a grand just to get her started.
The worst part is that she will be a better fly fisher than you. Rather than throwing the long bomb, she will surgically dissect a trout stream. Her casting will be so proficient that you will be trying to learn something from her.
You might end up like the guy in this video.
Seriously, this is awesome. Congrats!
