It's another push by Houston to host the Olympics in 10 years. The Houston 2012 Foundation officials announced on Tuesday a stepped-up Astrodome renovation plan.
If Houston is chosen for the Olympics, backers would convert the domed stadium, by 2007, into the world's first full-scale enclosed track and field arena. The cost is estimated at $87 million.
Members of a U.S. Olympic Committee site selection team will visit Houston and San Francisco in July. The other two finalist cities are New York and Washington.
