You will catch big fish all day on the Bighorn. The problem with the
warm water is...those big fish fight like old rubber boots. It is fun
to catch these monsters, but it's almost too easy and they act so
sluggish and unhealthy. You'll see what I mean.

Many locals here in MT consider the Bighorn in the same way they'd
consider a well-stocked kids fishing pond.....training wheels for other
rivers, maybe. The ease of catching these over-stocked monsters has
somewhat of an unnatural feel to it...but that's easy for me to say
since as a Montanan, I'm spoiled when it comes to the outdoors. And the
Bighorn does bring in the tourist dollars, I suppose. But that goes
back to the unnatural, over-stocked thing...

Anyway....you will have fun regardless of what I think. But bring
along a case of sunscreen to fish this river, as it will be between 90
and 110 degrees.
