Took the scenic route from Toronto to Calgary this May long and stopped along some rivers on the way for a few hours of fishing.
Minnesota Driftless
Henry's Fork, Idaho
Madison River, Montana
Missouri River, Montana
Was supposed to hit the North Platte and Snake River in Wyoming as well but the snow was dumping too hard so I moved straight on to the Henry's Fork. Wind River looked like a great place to fish too but the conditions were near their worst there. They'll be on my list for next time.
The Upper Madison and the Driftless Area should be on everyone's bucket list, totally unique fishing experiences!
