San Francisco? Have you been here?

I would suggest a brainstorming session. In CO there is a fair every year for precisely that. Brainstorming for small business. By small business I include self employment. However you might want to think in terms of a business and think creatively. You have a couple great interests to work with. SF is a great place to try different ideas. For example, I was interested in teaching and mindfulness so I got certified to teach Zentangle - a meditation alternative using drawing. I taught it for a while on the side. Mindfulness wasn't really a household word when I started. Now it is. I never thought I could teach drawing as I do not have a background for it either. Someone I met via Zentangle incorporated it in her life coaching business in Oakland. She also used to (or still does) teach nearly homeless how to be sufficient and incorporated it there as well. There are a zillion things you can do that you can't imagine until you start brainstorming and talking to locals in person.

If you can seek out groups for small business ideas you can use other people to help come up with ways to incorporate music or fishing into something unique. That link might help as well as searching meetup.
