I'm just rambling now, but I do remember something worth
mentioning. In my last post I mentioned a North Platte Wyoming
trip, below Gray Reef damn, where I used a Crazy Charlie for
weight and small blue beadhead nymph out on the end.

The other rig that really killed them that day (it was mid April and
the big
rainbows were active on shallow redds) was a Crazy Charlie
followed by a small, maybe 2" long red plastic worm from Wallmart.

That rig really drove my fishing partner nuts. I remember between the
two of us we caught close to two dozen fish at the put-in, before
sliding
the boat in the water. Those little red
rubber worms are hard to find. But they beat the hell out
of San Juan worms. Same concept, really. But way more effective.
