For those who are unfamiliar, RootsTech is believed to be the largest family history conference in the world. It is based out of Salt Lake City and attracts over 21,000 people internationally.
For those seeking more information about this conference, please visit their webpage at RootsTech.org. Tickets can be purchased at their site.
NOTE: Unlike in years past, the Expo Hall is no longer free for visitors. I confirmed this by emailing Info@RootsTech.org. If I remember correctly, their Expo Hall passes now cost (about) $19.99 (and may only be available to purchase in person).
However, the Expo Hall may be viewed for free if you reserve a Family Discover Day pass. This pass is free, but only good for Saturday, February 6th.
