Leanna, HPBA, the "Hearth, Patio, & Barbecue Association" is an international event for the manufacturers to showcase their stuff! This is the largest venue of its kind. I'm in the fireplace business, and I've been to the trade shows several times. A number of years ago the BBQ industry merged with the hearth products industry's making it a huge event! Literally acres and acres of bbq manufacturers demo-ing their stuff, giving out samples!
This year the trade show is in Nashville, I told the OP to take in some concerts while there!
