Over 300,000 people have visited the Sept. 11 museum since it opened little more than a month ago, exceeding expectations, officials said this week. Organizers see it as a strong start for the ground zero museum, which had faced questions about its $24 ticket price. The attendance total has topped projections by about 5 percent since the institution opened to the public May 21 and to 9/11 survivors and victims' relatives six days earlier, President Joe Daniels said.
