The judgment of the district court is affirmed on the basis of that court’s painstakingly thorough and well-reasoned order of February 7, 2006. All of the arguments that the appellants have raised before us are adequately answered in the district court’s order and no purpose would be served by repeating here what is said there.

This affirmance is without prejudice to the state law claims which the district court dismissed without prejudice.

AFFIRMED.
