Fairbanks is not a tourist type town. I often classify most visitors to Alaska as having a Disney mentality. The old, "we are here, entertain us, here is our credit card". Fairbanks is just a town where real people live and work and go about their daily lives. It has lots to do and lots of history but you will have to search it out for yourself. The river boat ride on the Chena River is fun and well done. The family that owns and runs it is an old Alaska family and not to cheesy at all, IMHO. A drive out to Chena Hot Springs is a good use of a day, go early and there often will be lots of wildlife along the road, stop at the musk ox farm, soak in the hot springs, good food there as well.
The oil pipeline has been of great importance to the state since the mid 70 and lots of good photo opps out around Fox, north side of Fairbanks. I enjoy prowling around the permafrost ice tunnel out by the university, built by the US Army and operated by the U of A. Don't know if you can get a key to the front door if you don't have connections through one of those organizations. I don't believe I will ever get the stink of that tunnel, out of my memory banks. LOL
Fairbanks is the land of the gold rush, the land that Jack London wrote about, land like that which the great Canadian poet, Robert Service wrote about in the Dawson City area of the Yukon. We only go to the Kenai to visit friends and to catch a few fish most trips as my wife nor I care for crowds of people, such as flood the Kenai much of the summer. Sometimes I think Anchorage must be empty of people for all of them being on the Kenai trying to fill their freezers for the winter.
Of all my favorite places in Alaska, Anchorage and the Kenai are just not part of that anymore. At one time prior to the oil pipeline days, we found both very enjoyable. At one point we owned a Kenai River property that had 150 foot of river frontage about 1 1/4 miles up stream from Soldotna. We bought it, with the idea of building a retirement home on it. But the big influx of people in the 70s and 80s changed our plans. LOL
But to each their own, I do believe. If the reasons a person is going to Alaska, is found on the Kenai or around Anchorage, then by all means go there.
