If you ever come to realize that dream, 3 days is not enough.... You need to fish the Snake River on the Wyoming side, then the South Fork of the Snake from the Idaho (Swan Valley) side. Then, you need to float the Henry's Fork though Box Canyon... The views of the Tetons from the Snake on the Wyoming side are truly breathtaking... It's one of the most beautiful and memorable floats you will ever have. If you can do it in the Fall, even better...
