Yosemite is a little strange because of how crowded it can be. You get tickets through Ticketron for crissakes.

But if you're in Yellowstone, you might seriously want to include flyfishing on your agenda. Even if you get a guide, it's something you might really enjoy. Just tell the guide exactly what you want - easier fishing for someone with little experience (don't worry, you don't have to do all that crazy casting to catch trout), out-of-the-way place where you'll probably not see anyone else, more small fish, fewer big fish, etc. I've found nothing like flyfishing to get me in touch with nature and the workings of an ecosystem. Being *in* the water is much different than drifting in a boat.
