I would have to go with Summertown. If you have never been there let me try to describe it. They have real oak bleachers on both sides and at one end. They have what i call the "Eagles nest", which is a press box high in the corner on the home side. It is considered 2 stories. The bottom floor is an office and up a very small flight of stairs is the "nest". With glass windows that slide open for a better view. This is also where the spot light comes from during the home team's 5 starters announcement. (All the lights in the gym go off and the spot light is shown). THis is also the time that cell phones and glowsticks are flashed. It really is a brilliant light show.
On the ceiling of the gym they have several oak arches that run from the home side to the visiting side.
THey have one of the smallest gyms in the state, but in my opinion it has the old school charm. And it is my pick for BEST LOOKING GYM!
