We took a road trip from Anchorage to Fairbanks and back, it was beautiful!
This oil pipeline is pretty impressive! 800 miles long.
Denali was a HUGE disappointment. Unless you want to hike the entire time, it's a terrible tourist trap. I have been to a lot of national parks and this one only wants your money. We only got to go ten miles in for a fee then it was tour bus for extra or park and hike a few miles. So we didn't get to see Mount McKinley in the park but later down the main road towards Anchorage.
I found the credit card idea fascinating, hadn't seen it before.
