largelili,
Congratulations on continuing your education at the University of Tennessee. Absolutely gorgeous campus. I highly suggest a good pair of walking shoes...and get ready for the hills in/around campus.
We moved to Blount County, Tennessee (20 minutes from campus) 7 years ago next month. Prior to that move I lived in the DFW area for 27 years. Though I have great memories of DFW, I find I don't miss the area. Candidly, I was in Houston about 9 months ago and honestly don't know how people put up with the traffic.
There are alot of Aggies in East Tennessee...and a few (such as ZooGuy) post on TexAgs. I'm scattershooting so here goes:
If you are an outdoor person, you will love this area. The Smoky Mountain National Park, which bisects the Cherokee National Forest, is about an hours drive from Knoxville. Great hiking and camping. My personal favorite is about 90 minutes southwest of Knoxville...fishing for rainbow trout on Citico Creek near Bald River Falls, which is in the Cherokee National Forest. More of a day trip, there's also Looking Glass Falls in the Pisgah National Forest, located about two hours east of Knoxville in Western North Carolina (not far at all from Asheville). And then there's the lodge at the summit of Mt. LeConte. Bottom line, there is never a shortage of places to go to experience Mother Nature.
Knoxville itself is only 250,000 people...and the 'metroplex' totals only about 750,000. Traffic is nothing like Houston, so get ready for a bit of a respite. The airport is actually located in Alcoa, TN, which is in Blount County. Only 12 gates, and airfares are not cheap.
With all due respect to my Aggie brethren, people here are much more fanatical about UT sports. In a way, it goes beyond obsession. You will grow to hate Creamsicle Orange. Also, the Strip puts Northgate to shame.
Say good bye to great Mexican food...Chuy's is about the only thing here. BBQ is OK if you find the right spot, but sweet pulled pork is common.
Get ready for lower temperatures, very high humidity, and alot less sun than you are used to. Knoxville is in a valley, with the Smoky Mountains to the Southeast, and the Cumberland Plateau to the Northwest. As such, inversions, particularly during January-February, make for many cloudy days.
People are very friendly, even more so than I ever experienced in Texas. But also, generational roots run deep here. It's not uncommon at all to meet locals who have an uncle that still moonshines, or to meet someone that remembers when they got running water in their home (I worked with two people in their 30's that didn't get an indoor toilet until they were teenagers. Weird to say the least).
As far as your boyfriend, I would recommend he look into the Oak Ridge National Laboratory in Oak Ridge, about thirty minutes north/northwest of Knoxville.
Driving distances to other areas: Nashville is 2.5 hours west, Atlanta is 3.5 hours south, Cincinnati is 4 hours north, and Charlotte is 4.5 hours east.
It's a slower pace of life and you'll laugh at some of the stuff that makes the local headlines. About three years ago, the announcement that the Cheesecake Factory was building a unit in Knoxville made headlines in both the papers and on the local television stations.
Politically speaking, this area is as right of center as it gets (the 2nd District of Tennessee has been Republican since the 1850's). I find it a bit humorous that locals who proudly display the Confederate flag have no idea of the area's history. During the Civil War, East Tennessee was loyal to the Union...and a black man by the name of William Bennett Scott, Sr. was the mayor of Maryville, TN in 1869. I guess that's the one thing I don't like about this area...Confederate flags on pick up trucks are not as rare as they should be...in my opinion.
But at the end of the day, we feel very fortunate to live here.
