I am taking a week and driving out to Cody Wyoming the week before July 4. No plans yet as to route, and want to spend the week car camping and trout/fly fishing on the drive out to Wyoming. Going to bomb it back on 90 in on Sunday July 5.

I have a real cheap spinner setup for trout that I use for backpacking/alpine lake fishing, but otherwise have no gear, and have no experience with fly fishing. I'm eager to give it a try and would love suggestions for places to fish, and what gear to get myself.
What is going to be an ideal setup for this? Where are places that I should not miss along the way?

As I have a week, I am open to pretty much any route on my way to Wyoming.

Thank you so much for your advice!
