Ritchie,

The salmon fly hatch is amazing. I love to fish it here in Oregon. Looking it up on google is a good bet to get a basic like history and photos. Every year when the hatch is thich it makes me think of the plague of locust from the bible... huge bugs everywhere, including all over you. They really like to crawl up your neck as soon as you hook a fish. But they are harmless and rather attractive.
