In my last visit to the lovely Lulu (way back in September), I walked many miles around Lu's campus (UT). While there, I noticed not only were that there were tons and tons of students walking to classes (OMG! UT is so big! I went to a college that has 100 times less students!), but that were also tons of students using the bus system.
Knoxville's transit system is called KAT (Knoxville Area Transit), and I was impressed to find out that they use alternative fuels in the running of their buses. In further research, I discovered many of their buses are ran on biodiesel.
I am so happy to make this discovery. Especially, since I found it in a place where I did not expect it. I took a vacation from Asheville to Knoxville, and what did I find? Some of Asheville's best values right in the heart of a giant college campus. :)
So the next time you are in Knoxville make sure you use the bus system. You'll be helping out both the city of Knoxville and the planet Earth.
