The convention bureau said conference attendees will occupy nearly 2,200 hotel rooms during their stay, and the conference will have an estimated economic impact of more than $1 million for the city of Sacramento. </p><p>The list of speakers includes U.S. Secretary of Agriculture Tom Vilsack and Sacramento Mayor Kevin Johnson. The conference-closing gala will feature internationally known entertainers Penn Jillette and Teller.
