Searching around I couldn't find a thread devoted to this, the hobby that you can enjoy indoors and out.
My favorite trout killer:

I remember growing up and my mom tied lots of flies. These were the best in my area so they will always hold a spot in my heart.
I have a basic kit that I use to mess around and experiment with different designs. I don't have a fly rod anymore, so I don't use them, it's mainly a relaxation thing for me, although occasionally I'll head up to the creek and use those little clear bobbers that you fill partially with water and throw a few flys in.

What are your favorite flys / materials / fishing spots and memories ?
