Idaho, Wyoming, Utah and Colorado are just a handful of the general areas you could score a tag. Some you could get OTC but most you'll need to apply for the draw, that doesn't mean you'll need a boat load of points though. General unit tags are likely what you are looking for. If higher open country is what you are into then any of these states will produce you a tag given you get into the draw In the states that are managed in that fashion. Like stated above, narrow your search down a tad bit before asking the blanket question. Most won't give you narrowed answers to your question without feeling like you've done your part.
Sit tall in the saddle, hold your head up high, keep your eyes fixed to where the trail meets the sky...
