What do fly fishers like?

Hello all,

I'm in the process of creating a website whose purpose is to help
people do nice things for each other.

Many times, you want to do something for someone, but all you know
about them is that they are interested in a particular hobby or
activity that you don't know much about.

I'm collecting information about as many different hobbies as I can.
So...two questions.

1. What do fly fishers like/need/want?
I'm looking for a list of things that someone else could pick out for
you that you would really enjoy receiving. This can include items, gift
certificates to particular stores, magazine subscriptions, books,
favors, trips to events, etc. Anything that you would find useful
and/or desirable in your capacity as a fly fisher. These don't have to
be "bought" items. If you really need lots of empty egg cartons, put it
on the list!

2. If I was married to a fly fisher, and wanted to better understand
what they are talking about over the dinner table without actually
becoming a fly fisher myself, what books or websites should I look at?

Any information would be appreciated by myself and likely by the
families and friends of many fly fishers! The guys over in the
woodworking newsgroup did a great job on their page. I have high hopes
for the fly fishers!
