Recently flew out to meet my cousin who lives in Bozeman, MT to embark on 5 days of floating the Missouri River out of Craig, Montana.  We also met up with some of his friends from Missoula, MT and we had a Spey Clave.  We trout spey fished the entire trip and were able catch a good quantity of bows & browns.  The scenery was absolutely spectacular and very little fishing pressure.  For those who are looking to travel to a great area to fish I would put MT on your bucket list.
