Where to go for wildlife photography?

This year we are headed to Norway for two weeks and the trip planning is done except for flights. Now I'm itchy to start next year's planning. One of our main interests when we travel is wildlife photography. We will be flying, so distance is not an issue. We've been to Olympic, Yellowstone, Grand Teton, Glacier, Waterton, Banff, Jasper, Badlands, Saguaro, Fundy, Shenandoah, Great Smoky Mountain and Acadia national parks, Custer State Park, most of New England, all over the Canadian Maritimes, Alaska, North and South Carolina, Virginia, Florida, Hawaii, St. John (USVI), Denmark and Iceland. All thoughts and suggestions are welcome. Preference is North America (US, Canada). Along with the wildlife photography we like hiking, fishing, canoeing, scenery, puttering around shops, museums, history, and just general exploring. Willing to revisit any of the above places if there are places that are not normally visited. Feel free to think outside the box. Thanks!

Well this is outside of the box you specified, but if you truly want wildlife, then Africa is the place. We did a 3 week safari trip in October, 2014, to Botswana (Chobe River and the Okavango delta), Zambia (Kafue River), and Zimbabwe (Hwange Park and Preserve), and it was spectacular. We booked through Overseas Adventure Tours. From the amazing quantity of wildlife, to the spectacular sunsets, to taking a helicopter ride above Victoria Falls, the whole trip was amazing. A few shots (and these are just the smallest sample - I came home with more than 2500 images):
