A 30-06 will allow to go after everything you want in the lower 48 as long as it is not too far away. I would not shoot a 30-06 at more than 300 yards during a hunt. On the range it is another story.
Since you are driving you cannot go too far. That excludes Canada, Alaska, Northeast. You can try an Elk hunt if you can get a tag.
Note: I personnaly hunt first for food and second for mount. Go through the list of outfitters. You can find a good list at
http://www.gameandfishnetwork.com/Outfitters/r=West.html. Colorado and Wyoming will offer a nice selection of hunting vacations.
