Don't mess with Texas
According to Iron Maiden's official site, the band will only be performing from July 15th through August 20th as part of OZZFEST 2005. If the listing of dates is indeed correct, the bands last show will be in San Bernadino, California at the Hyundai Pavilion due to scheduling conflicts in Europe - namely their August 31st appearance in Dublin, Ireland.
It appears that the last 7 dates of the tour, which stem from New Mexico to Florida, IRON MAIDEN will not be performing:
August 23 - Albuquerque, NM @ Journal Pavilion
August 25 - Dallas, TX @ Smirnoff Music Center
August 27 - Woodlands, TX @ Cynthia Woods Mitchell Pavilion
August 28 - Selma, TX @ Verizon Wireless Amphitheater
August 31 - Nashville, TN @ Starwood Amphitheatre
September 2 - Charlotte, NC @ Verizon Wireless Amphitheatre
September 4 - West Palm Beach, FL @ Sound Advice Amphitheatre
