I live here in Louisville and if anyone has any questions or would like any dining or tourist information, just let me know. Louisville has a ton of hidden little venues that offer great stuff at a great price.
My biggest tip for anyone going to the DCC...pack a cooler and forget about eating at the hotel. The food is horrible and overpriced. Grab some lunchmeat and bread at a local Kroger and you will thank yourself later.
Other areas of interest you might be interested in: Louisville Speed Museum, Louisville Science Center, The Ali Museum, The Frazier History Institute, and for all of you music buffs out there...Ear X Stacy is a music store that has just about any cd that you ever wanted to buy. It is a real cool hippie store and they have tons of "non mainstream" music. It is located on Bardstown Road. I would check out Bardstown Road for its unique dining, shopping, and hippie venues. Cafe 360 has the best and cheapest breakfast in town if you are in the mood for it late at night. They also have hookas for you hippies.
