Yes. Go to Paducah. Don't miss the Quilt Museum.
Paducah is a "whole town" event. The show itself is fantastic - some of the finest quilts I've ever seen. For quilters entering a show, it is one of the premier shows. Naturally tons of vendors. But Paducah is also the home of the Quilt Museum and it's a must see.
Also in town is Hancocks of Paducah - don't forget to explore the "back rooms" for really good sales. Eleanor Burns has a store and she holds a tent sale with entertainment. Another shop rented the warehouse across from the Museum and had a fantastic sale on a lot of stock (one table was nothing but assorted white-on-white and white-on-cream for $5.00/yd).
Mostly ... go for the museum and the quilts at the show. Simply blew my mind.
