There are a bunch of areas in Colorado that don't require any preference points and have guided hunts. I have never used a guide, so I will leave that to others who have, but if you do some research you should be able to find some good ones. I would be sure to get a bunch of references from any guide you are considering, and make sure those include people who were both successful and not successful in their hunt. I would also talk to the guides ahead of time to make sure you inform them of your health and make sure that the hunting situations they put you in will be adequete to what you can do.
