The NAHB (home builders) show is at the same time, if you hit all three shows you'll have a lot of info packed into one week. Info:

Personally I like Surfaces, even though it has competitive products like wood, carpet, and vinyl represented that can be a positive too. For sure you'll see something that will start your wheels turning about a better way to address a problem.
I'd also be remiss if I didn't mention that I'll be working with Noah Chitty (Crossville) and Ben Szell (European Tile Masters) once again this year in talking about Thin Tile. Bill Griese (TCNA) and I will also be giving a talk on using tile in LEED projects. I just tried to find some links on the Surfaces web page but it doesn't look like they're all listed yet, I'll stop back around with more info.
