At our house the arrival of the new year's fly fishing catalogs is known as "research". As in, "I'll be a little late to work today because I am at home doing 'research' ".
It seems I once received more than a dozen catalogs. But in recent years the number has declined to just a handful. Likely, the Internet has changed things for some companies as has the cost of publishing a catalog and the cost of postage. And I also simply don't buy as much fly fishing stuff anymore, especially now that photography has entered the scene as a serious hobby.
I see that last year I received catalogs from Hook & Hackle, Stone River Outfitters, Feather-Craft and The Fly Shop. So, there's hope that more winter research will arrive. (I think Dan Bailey has dropped me... and for good reason as I have never purchased anything from them.)
