Any Orvis shop will carry it, except the Palo Alto store. I picked up the last bag of snow shoe rabbits foot Saturday during their moving sale. They have 60% off all of their fly tying stuff until it is gone. Everything is else is 40% off. Got to love Orvis when they move. As for their usual pricing, I didn't find it any more or less than the competition. Besides, my buddy is an Orvis poster child with the exception of his Simms vest.
BTW, Harry, that is a very nice tie. And if you won't say it, I will. Harry has his tutorials on CD. Snap them up for holiday gifts.
