Chattanooga is beautiful country. With the mountains being a part of the area, lots of different things to see and photograph! I live in the north part of the Atlanta area and we try to get to Chattanooga once or twice a year since it's not that far.
Welcome to the forums! Aslyfox has already given you a lot to look at, I'm sure

The K10D is still a wonderful camera, I have one and love to use it despite it not being "the latest and the greatest". Those older cameras had a different sensor technology (called CCD) which seems to have been tailored to bring beautiful colors out of any scene.
