My brother has the CD and I've only used it on a limited basis. It has some good info but I wouldn't rely completely upon it. I will say that if you're a non-resident, I would take advantage of as many resources like this as possible. Since scouting here in Colorado is probably impossible for you, the price is actually minimal regarding the info you'll get. I would use this info in combination with doing a few other things like researching the DOW's harvest reports (available on their website), calling and speaking directly with the DOW and then trying to ask as many questions as possible on sites like this one.
I can definitely relate to your Dad getting older. I'm in the same situation with my Dad. How well does your Dad get around? Will you be hunting on foot or by horseback. That kind of stuff will also help you determine what unit you'll want to hunt.
I don't claim to know everything but living here in Colorado and having researched and scouted a lot of areas, I would be willing to help you find out more information as your search progresses. Just let me know what you need and I'll let you know if I have any info. Good luck.
