Spent many a day on the Prickly Pear. It is a great little stream. As you know it is one those little gems that it seems only the locals know about and the guides don't take dudes to. Caught many fish in it on caddis imitations.
You ever fish the Little Blackfoot, Flint Creek, Wise River, Thompson River, North Boulder River below the springs, lower Madison below Ennis, that great little public spring creek out of Three Forks (which I will not name), upper Sun River, Highwood Creek, Monitour Creek, Clark's Fork below Superior, or the extreme upper Clark's Fork? These were some of my favorites. And then there is the great white fly hatch on the Jefferson in August and early September. The Missouri was always good to me but the boat hatches and the inconsiderate guides chased me off it until after Labor Day in the late 1980's.
