Oregon has some great wineries so I would think you will get some excellent hands-on opportunities.
I am sitting on my hands watching the snow melt around my neck of the woods. I have gone out twice and between the icebergs floating by and the wind it has not been what I would call easy fishing.
I have learned to go with pre-tied pieces of tippet with a loop on the end to make changing flies easier when my hands freeze up into claws.
My fly collection has grown exponentially but I tell myself I can stop accumulating flies at any time I want....just not today.
I went to a fly fishing show last weekend and I encountered a tier who incorporates silicone legs into his stonefly impressions. They are marvelous to behold. I think he molds his own silicone legs to keep down costs.
I don't know if the fish will care about the realism, but I sure do.
